Not even Vivienne blames Anders' actions on all mages, she just points out that the two will be associated because of the timing. But the mages were in danger of being extinguished one by one. I'm already familiar from the Dalish threads that people think that's something you should just swallow.
I do agree that the Circle or something like it is necessary in societies shaped by the Chantry's bigotry. It would be nice for Viv and others to acknowledge that they created the conditions under which mages have to be locked up for their own protection. The ones who don't have powerful political patrons, that is.
I wouldn't either if Fiona didn't follow in his footsteps. And unfortunately she forced the war on the rest of them by ticking off the douchebag templars purposefully. It isn't fair, but Fiona made this war what it is. Do I expect them to accept death, no not anymore than I'd blame a bear for fighting back, but I'm still going to kill it if it becomes my enemy. Someone should have shoved a lightning bolt in her or something, lol. The majority of them weren't pushing for separation and war like she was. But that's the leader they got regardless.
And don't equate me to them, I don't expect the Dales to accept anything. I want them to rise to the occasion. No one wants to see a dog kicked around all day. It's just sad. However, I do see similarities with this issue and the one with the Dales not helping the Orlesians during the blight, I'll give you that much. But as much as people say Tevinter isn't this or that, I can't help but look at how things turned out. Tevinter may have disowned the Venatori... eventually... and they took their sweet sweet time doing it I might add, but Dorian pretty much says himself they simply disown or villainize whoever is convenient to them. So I have a hard time believing the guys who only pretend to dislike blood magic and demon rituals are no less trustworthy than anyone else. Not everything the chantry says is a lie, as we learned first hand from Dorian's father. So again, I can understand the decision, same as Anders who I can actually understand, but I still find it very stupid. The Dalish not helping the Orlesians was perfectly understandable, but very stupid as well.
As for the rest, nothing about the chantry made demons be attracted to mages. Granted, the harrowing is indeed retarded, and ideally, I'd only put troubled mages in circles, not every one. But even skilled mages have the chance of attracting and becoming demons as abominations. If it's either or, I choose the circles.
