Also, I would think that people who get triggered by certain kinks, would want to stay far away from discussions about these things. When something makes me uncomfortable I don't feel the need to talk about again and again and again...
Especially since it's really not very likely that you're going to change someone's mind about their kinks. So I don't see the point in someone telling someone else that their kink is disgusting. This is not news. There are always going to be people who are repulsed by some kinks and there are going to be those who are turned on by them. That's life.
That doesn't mean you can't complain when someone is being an ass or isn't using warnings for their fics. You can't warn for everything but certain things like rape or pedophilia should have a warning. Unless, of course, you want people to think you're an asshole and complain to you. (I wouldn't be surprised.)
On the other hand people who whine about having triggers that absolutely no one could expect and therefore warn for are fucking ridiculous.
