Taking into consideration what DA:I says about the Qun and their roles...

Well, it's easy to see that the language the Qunari use has been carefully chosen to opress people and obscure certain facts about its society.

Take, for example, the social construction around individuals who choose to leave the Qun. To be Qunari is to be a real person ('bas', the term for non-qunari, we are told in-game, means 'thing'), and if you leave the Qunari, you aren't just "no longer" a person, you *never were* a real person to begin with, and thus, the Qun argues, not only has it not lost anything, it has actually become stronger by expelling weakness. Because if the Qun admits fault of any kind, the whole system immediately crumbles.

It's blatantly obvious that there are individuals and even groups within Qunari society who disagree with or have different interpretations of the Qun, either whole or in part. But the language of the Qun comes with a built-in method to write off dissidents as "not real Qunari", just like the Chantry (or most real world religions, for that matter), can write off disagreement or dissidence as heresy or sin.
