1. The person masturbating in public is making you party in something you want nothing to do with. A public suicide is making you party in something you want nothing to do with. The person masturbating in front of children is making them party to something they want nothing to do with. The suicide shooting his brains out in front of children is making them party to something they want nothing to do with. And, since you mentioned "intent matters": someone who shouts "THIS IS YOUR FAULT!" at someone before offing themselves has a pretty explicit goal of causing extreme trauma and guilt to another.
2. Alright, let me make this clear: domestic violence, child abuse, and depression are all serious issues that should be better addressed. The latter, for me, is also a personal issue. The fact that you act like it isn't, and I just don't want people to kill themselves out of virtue signalling or because I'm some kind of sadistic monster (or whatever reason you assume) shows a very distorted pattern of thinking.
3. If seeing a suicide is more traumatizing than seeing masturbation, you would think you would see it as worse, not better, to expose a child to that.
4. And, as usual, you lapse into your misanthropic "I'd rather live in a post-apocalyptic shithole than a civilization because then at least all of my biases about human nature would be confirmed" rant (NOTE TO CORBIN DALLAS MULTIPASS: since you insist on policing me, I defy you to read Sprig's post history, especially on the topic of human civilization, family, and behavior, and say that the above is more than mildly uncharitable to his greater worldview.) I will reiterate: maybe you should just post about the lolcows rather than talk about this sort of thing. On my behalf, I should probably stop responding to you, because in my opinion, people who have no skin in the game of human society shouldn't be taken seriously when it comes to... well, anything involving human society. In conclusion: I sincerely wish I had enough money to grant your wishes and ship you to Somalia, which by your standards is the most honest country (although not perfectly honest, since it hasn't devolved into a perfect Hobbsian war of all against all where anything human is a hindrance to survival.)
