All of this brings me back to Dragon Age 2, something that Aveline said, she quotes a part of the Chant in which it says something akin too "The less he does, the more he proves." to which Aveline basically says bullshit. She's having a minor crisis of faith but doesn't get hung up on it, even being kind of whatever-ish about whether or not Wesley is by the Makers side or not. We haven't really seen many people leaving the faith in DA, but we have seen people leaving the Qun left and right, which is weird because one is tangible while the other isn't. I hope one day we see a equal amount of former Andrastians questioning and leaving the worship of the Maker.
Alright, at this point I have to ask exactly what it is that you find so offensive about the Andrastian faith, because I simply do not understand what you're getting at... you don't understand why people would leave the Qun, a philosophy (not a religion) that dictates who you are, who you will become, what you will do, who you will marry, where you will live, and every other aspect of your life from birth until death? Seriously, you don't see any reason why people would not want to live that way...? At most, the Chantry can be accused of worshiping a god that they can't prove is real. That's it. I don't see any oppression of the common people or anything at all that would cause people to question the Maker or the Chantry's teachings... perhaps if there is a scientific revolution in the near future, then you might see people questioning the Maker, but this is a medieval society we're talking about. Unless I'm missing something, there is no reason for them to abandon their religion.
