Are they targeting specific rich people in a dedicated and persistent fashion to the point that said rich persons kill themselves? No, that's not happening. I've seen posts of the type you've described. They're almost always dead/banned/shadowbanned. They're much less frequent than any one of anti-black, anti-gay, anti-jew, or anti-trans comments... which are almost always dead/banned/shadowbanned as well. This site does not remotely compare to KF.
Kiwifarms was founded to troll and harass a specific webcomic author. From there it evolved to target and harass specific people or communities.
Surely you see the difference here.
Why should we?
Society has been doing pretty fine with some fuzziness until now. Sometimes something really goes to far and they end up not hosted anymore. That’s the system working, not it failing to work. Well, that came a bit slowly for kiwifarms sadly but I’m glade sanity prevailed in the end.
There are threads here where people call for wealthy peoples heads. Did that cross a line? Could we say it about other people?
