I was just saying last night how stupid it is that people get so worked up over a political issue in a video game. How about you put aside whether you think mages should go free or not (considering they are not actual people and Thedas is not a real bloody place) and focus on the characters, their complexity and possible hidden secrets, the future relationships, the richness of the narrative, the various choices we may be presented with?
But nooo people gotta get on that soapbox and talk about utter nonsense.
I'm not saying the mage/templar thing isn't important; sure it's important; it's what creates narrative conflict and invites us to create many different characters with differing beliefs. But arguing passionately about whether mages should go free or not is like arguing which side to choose in Skyrim. Which... actually I'm sure people probably do argue passionately about
I hate to say it, but, get a life!
I don't want to sound rude, but I honestly don't see the differences between discussing the characters or certain plots like the mage-templar war. Characters discussions can get heated too. For example, in the discussion of the war in the Vivienne thread the discussion was quite civil and moderate. I agree that the topic often goes too far (it is part of BSN holy trinity of war, with Cerberus thread and Romance thread

), but there are plently of people who discuss it in a normal way, and I don't see why they should 'get a life', more then the people who discuss characters.
Again, I don't mean to be rude.
After absorbing the "fledgling Inquisition" idea a bit more, I still just can't see how Cullen can already be a part of their organization before they talk to Varric. Of course, they don't go talk to Varric to find out they are wrong about Meredith, etc; they think they know what happened. But, you'd think a thing like "my boss turned into an abomination, flew, and then turned into stone" would be something you'd mention to the Divine and her secret agents worried about Kirkwall. I stand by my lengthy and annoying arguments over the years that there's just no way they talked to him already, or they talked to him and didn't believe him/didn't ask the right questions. None of that suggests Cullen is bosom companions with Cass and Lel at that point. Hmmm....
For the moment, voting for "recruit Cullen and his faction afterwards." 
I'm not sure how Cullen is recruited in the Inquisition, but I don't think he's recruited afterwards. Expecially since the Inquisition was already formed in some ways, I don't see it likely that it won't have a general/army leader already, and that Cassandra/Inquisitor would recruit the general later (and it doesn't make sense to me that you put someone external to the Inquisition in that position. Yes, we are put at the head, but there's a sort of a reason).
Plus, I don't see in which group he'll be in if he was outside of the Inquisition.
I Agree that the situation is strange, but I think it is because we miss some info on the event between DA2 (Meredith's end) and Varric's interrogation.
