1.First of all, how they would knew from where Meredith would take red lyrium it wasn't a public knowledge.Second deep roads are incredibly dangerous and they wouldn't even have location of it.Third once again even if they did find it likability they would transport it on the surface and mantain regural occurrence would be incredibly low.Plus, red lyrium is a substance all you need to do is get rid of it on the surface, even if get rid most of it should be sufficient enough to decrease danger by large margin.
I already told you there were many people who knew the location - Bartrand and his cronies, Hawke and all his companions + Bianca. Any one of them could have told someone who would see a business opportunity - or like what actually happened; Bianca told Corypheus and that's how Red Lyrium spread to the surface. It's not impossible scenario to imagine - quite the opposite. Deep Roads are dangerous, but like I already said where there is a will, there is a way. Many people travel to Deep Roads all the time - some looking for treasure or riches, like Bartrand and Hawke. There will be people looking for Red Lyrium as well. You forget how the Red Lyrium grows - it spreads fast and you can 'farm' it (like Imshael). Carta is already distributing it, we find out about this in DAI. Why would they stop just because Corypheus is gone? It's even more valuable now.
2.Evidence is simply lack of evidence that something was in case, while every source suggests otherwise.It is your job to prove existence of something, not mine to disprove it.
What do mean 'every source suggests otherwise'? Only source you have on the matter is Chantry's word. You obviously cannot prove that darkspawn didn't already exist. Humanity only learned about them once the first Blight began, doesn't mean they didn't exist before that. Just like every year new species of animals are discovered - do you also claim they didn't exist just because you didn't know about them?
3.Problem was that mages existed even if everyone was a mage problem was still mages as they were still threat to world safety.Current Thedas have much less mages but problem are still mages that constantly threaten the world.Solution is simple remove mages from equation will/would largely decrease worlds problems.
You make no sense. So you say it would have been better if all the ancient elves had ceased to existed? Well, that would be interesting because if Solas had never existed he would never have created the Veil and then there would never have been humans, dwarfs or modern elves. Only spirits and demons - and they would have nothing to reflect except the hollow emptiness of the world.
Life is glorious and wild. Magic is natural part of the world - remove that and what is left? Chaos is natural - order is unnatural. You're fighting a losing battle.
4.Yes it is, magic or mages draw demons from the fade regardless of how they use their magicThen there is huge amount of potential for abuse and ignorance with disastrous effects.No it isn't just like a soldiers, i explained it many times soldiers are nowhere near as dangerous as mages, as evident that not a single non-mage created world-threatening disaster in the setting.How many times i will have to repeat same thing, just because chantry lied about some event deson't equatate to them being wrong here, sure it would diminish credibility of their statements overall but in that case Chantry was proven mostly correct by Corypheus and fate of magisters that went to the black city, chantry was spot one not only on events before they went to the black city but also after they went to the black city, with exception of maker part that Corypheus denied.Once again there is not a single piece of evidence that darkspawn existed in Thedas before, it is your purely wishful thinking.
Anyone can be possessed - not just mages. Their connection to the Fade makes them easier target, but there are ways to avoid demonic possession or save someone who has been possessed. Like Connor. That was thanks to blood magic, by the way. According to Solas blood magic weakens the connection to the Fade, so that could also mean that Chantry's claim that blood magic attracts more demons is just another lie.
I already told you, if you feed templars Red Lyrium you get soldiers who are far more powerful and dangerous than normal circle mages (most of whom can barely light a fire with their magic, thanks to wasting their gifts rotting in a prison and being allowed only to recite the chant day after day, living in fear of themselves and what they could be capable of, because of Chantry's stories about evil maleficarum and the rite of tranquility).
Chantry has no credibility left. The only part they were correct was the magisters entering the Fade. Corypheus himself said darkspawn and taint existed before he ever set foot in the Golden City, how many times must I repeat that? You can choose to not believe it, if you wish, but that doesn't change the fact that there is evidence to suggest otherwise.
5.Proof, no but it is reliable to think at least some returned on their own to the circles (As Varric pointed out many Kirkwall mages blamed Anders for situation) and considering public opinion about magic (if i recall there is war table mission where Leliana suggests let mages go so they can return after they see living outside circle is very hard and they return) it was sane thing to do.Then there is matter that most likely good deal of mages were recaptured.
Most likely none of the mages were recaptured. Not alive at least. Hawke would have been there to protect them (and Anders, if he lives). No mage in their right mind would let the templars take them back to the Circle where they would be most likely made tranquil. All the Circles fell anyway when the rebellion truly began.
6.It is not mistreating them to take reasonable precautions.- Cullen
Mages live in most luxurious places in Thedas, if that is mistreatment i want that to.There is a little evidence that Templars mistreat mages on any other basis than individual.Even in Kirkwall there were only 2 templars known of abusing mages.Plus, you completely ignore fact that chantry preaches as well that magic is a gift just to push your false narrative that you support with false claims and half-truths in order to invoke emotions of others so they join your narrative.
Oh yes, Spire and it's dungeons where mages like Cole were starved to death were truly such a paradise! Or Gallows, a former place for slaves, where mages were locked in their cells and tortured by men like Alrik for fun. So luxurious! There is every evidence, so many reports of mistreatment of mages and so many times the Chantry and the Seekers simply turned a blind eye. Chantry teaches that magic is a corrupting influence in the world. They promote ignorance and blind hatred of anyone who just happens to be a mage. It's their fault normal people fear magic and treat mages like they're monsters instead of woman and men just like anyone else.
7.How exactly you jumped from Dalish whitewashing themselves in this war, spreading lies about Dales and war, to discussion who's guilt it was?Dalish don't know jack, their entire culture is based on lies and whitewashing their own failings.Considering that circles frame much more mages than dalish that deal only mostly with 2 mages per clan and that we spend much more time with the circles than dalish it is only understable, im not ignoring it im pretty sure i did acknowledge circle failings and lot of room for an improvment but compared to dalish circles at least contained it's outbreak at least until pro-mage divine send whole system to hell with her stupidity.
Dalish practice magic freely - and so does Tevinter. If magic was so bad as the Chantry says there would be no dalish clans left and Tevinter would have demons running all over the place. That hasn't happened. Tevinter also has a Circle - a place for study of magic and way to seek knowledge. They also have templars - instead of the corrupt Orlesian Chantry who serves the whims of rich and powerful orleasian nobles, the templars of the Imperium serve the mages and magisterium directly. That is how it should be in every corner of the world. Mages can clearly take care of themselves they do not need the Chantry. Such a frightening truth it must be for them. That is why they spout their propaganda against Tevinter and have more than once declared Exalted March against the Imperium - to no avail, of course.
8.Orlais didn't invade Dales, stop spreading lies.Dales invaded Orlais and Orlais and chantry only retaliate for that.Unless you want to tell me that Orlais should just allow elves to kill and invade them it was very much justified.Chantry failed thanks to Justinia and Leliana that as i said sent entire system to hell.
It was racial and religious persecution - and when the elves tried to get away from them the Chantry would unleash their templars to attack them. The Dalish merely protected their kingdom from orleasian invasion by pushing them back beyond their own borders. They captured areas of significant importance to held back the humans invaders. This of course gave the Orlais the perfect excuse to claim elves attacked first (all lies, the violence had been going on for years, what happened at Red Crossing was just a convenient excuse to start the war they had longed for so long) and thus justify what they did.
Chantry was doomed to fail from the beginning. I'm only surprised it was left standing after everything that happened in DAI (a shame, really, but on the other hand it will be interesting to see if Leliana is able to completely transform it from within).
