@EricFielding This is partly because white Europeans and white Americans hassled Black US users who popped in here in the 2022 Twitter migration. (To make matters worse, some white europeans accused Americans of "making race a problem" here, i.e. took the line that people pointing out racism were the problem, not people being racist. For some reason there was less evident racism with fewer Black users 🤔)
I'm simplifying a bit in the interest of character limit, but I saw a lot of this firsthand
