The problem with "Toxicity(TM)" is, its always and everywhere, not always open but more hidden and private.
Some people are jerks, but most toxic people just don't know how to handle their toxicity in a harmless way or are to emotional for that.

If people would learn to calm down and vent their toxicity into a side channel like to friends, diary, this thread or something of that kind instad of open ranting in a duty emotianally fired up, the open toxicity would be far less.

The next step would be that everyone starts to take responsibility for their actions.
If i see the content I entered is to hard for me, I excuse me and leave, and this schould be done by who people who come to know that they entered content to hard for them.
Then they can train to get better or hope for unsync.

Open ranting, hate speach and swear words are as toxic as sneaking into inappropiate content.
