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.
I don’t know when you encountered this but “safe space” has been a meme for quite a while. So there’s a good chance the “safe space” you found was actually the exact opposite and using that term to mock “SJWs” and people who get “triggered”.
That makes a lot of sense, actually.
