I once entered a “safe spaces” Discord server with literal flowers and stuff. It looked very innocent and welcoming and it was just for gaming. Turns out, they were making fun of their members on it, fake-crying to mock a depressed user, and kept telling the users to “let them see their cuts”. It was so disturbing. These were literal 18-20 year olds, too, and I was like 13.
We have a human tendency to take safe spaces to mean “safe space for me, even if I make others unsafe”.
South Park made a good satire of exactly this, where Cartman immediately realized it meant he could continue being offensive and “safe space” away anything he didn’t want to acknowledge
