It irritates me how any criticisms are usually just deflected with the character saying, "in your culture, blah, blah". For one, and maybe most glaringly, it seems to usually largely only apply if you're playing a human character, the only ones with any real power to make the "rules". Nagging an oppressed minority for being oppressed in their homeland, as if that's as bad as being part of an oppressive majority somewhere else and still towing the party line, is pretty absurd. They're not really responses tailored for other races. The alienages and similar issues characters bring up don't really apply to someone playing a Dalish elf or Tal-Vashoth character. I wouldn't honestly say that's "their culture" at work.
But, secondly, what if you hate those aspects of your own culture and would do anything to change them? What if you spend the whole game fighting them? It seems like a massive brush off. It doesn't answer how the character actually feels, not really. I want to ask them if they're actually willing to fight to change these things, or if they just think, "oh well, everyone has problems, no sense worrying about it". The brush off just seems like a cheap dodge and you never get a chance to respond with any real opinions on the issues they bring up. Basically, I think these sensitive issues could probably be handled better, but I guess it's just an issue of limitations and not having time or resources to flesh out multiple paths of arguments for various beliefs. I still wish they could at least be clear on whether or not they think these things are worth fighting against, rather than just defending them as "no worse" than (maybe not even really) your character's cultural flaws.
I always play a character that pushed for social reforms and supports those that face undue oppression wherever I can. What I really want to know isn't if they think there are equitable flaws in the Andrastrian majority countries we've visited so far. I know there are major problems there and my choices in game should speak for my belief that those things should be actively fought against at every opportunity. What I want to know from my companions or other NPCs is whether they feel the same about flaws in their own cultures. Do they believe those things are worth fighting against, or do they just accept it? And, if they just accept it, that's what I want to challenge. My problem with it is that it always feels like the game assumes the only reason you'd needle a non-Andrastrian about the flaws in their culture is if you're trying to leverage some moral superiority for Andrastrianism. For the type of characters I play, that couldn't be farther from the truth. I feel like these responses miss the point for my intentions, which makes them ultimately really unsatisfying.
