As I see it, the problem of perceived "extremism" is that many of the issues dividing Thedas are essentially binary. Either mages are controlled by Templars, or they aren't. Either the dalish can live according to what's left of their culture, or they can't. You either follow the Qun, or you don't.
There is no middle ground on some of the world's issues, and I think that is by design. I think that rather than look for "moderation" what I would rather see is basic reasonableness. It may be that a character's unequivocal "yes" or "no" answer to a question dividing Thedas during Inquisition is well reasoned--show me that. Let me see, if I look carefully, why that position makes sense to the character. If I see problems with the logic, let me change someone's mind.
I have no problem with absolute perspectives, necessarily, but it becomes tiring to be surrounded by zealots and dogmatists.
