I think you've confused several arguments for another thread. The only real thing to talk about here is about what the moderation policies do, which is simply outline that, effectively, someone can't just be an ass to someone. Passively or agressively. This isn't an automatic moderation thing, as in the end it's up to the mods to make a verdict on any post that is reported.
As for your whole point on triggers. Not - really sure at all where you're coming from here. Because there's a huge difference between trying to censor conversation, and not wanting people who have yet to recover from scarred events to feel like utter garbage. Because, you know, that's also part of the whole 'don't be a dick' in the rules.
