If I lived in Thedas, I'd be 100% pro-mage freedom and nearly 100% anti-chantry. Basically, I'd be best buddies with Anders.
Nothing justifies what is done to mages in the world of Thedas. They are treated like less than human. Cullen even says as much. And from what we've seen from templars like Ser Karras and Ser Alrik, we know that some (not all) templars abuse mages to a sickening degree. Ser Alrik is clearly a rapist, and Ser Karras is a bloodthirsty sadist.
There are also the many indignities that mages have to suffer while living in the Circle. They have little to no privacy, something which most of us take for granted. They can't have open relationships with other mages (and obviously other people either since they are confined to the Circles), and if they do end up pregnant, their child is forcibly taken from them! That's not even mentioning their complete lack of freedom. How would you like to be locked up in a tower for the rest of your life for something you might never do? It reminds me of the movie Minority Report, where people are arrested and imprisoned for crimes they haven't even committed and may not even ever commit (as the movie later shows).
In the real world, we deal with criminals after they have already proved they are a criminal. We don't go locking up people that are at risk of being criminals, because that would be insane and inhumane! Why should it be any different in Thedas? But mages can become demons and do horrible things, you say? Well so can any madman with a gun or a bomb in our own world, but we still don't lock up people because they have risk factors for being a criminal (being abused as a child, having certain mental illnesses like bipolar disorder, etc).
You can probably tell I feel very strongly on this issue, which is funny, because it's not even real, but even though it is fictional the mages' plight has many real world analogies, like slavery.
I'm also anti-Qun for very similar reasons. They are even more sickeningly cruel in their treatment of mages, who, by the way, never had the choice to be mages. They are simply born thus...you know sort of how certain people were enslaved because of another attribute they had absolutely no control over.
I'll stop ranting now. lol. But I felt like I had to get that off my chest somewhere, and this was as good a thread as any to do it.
