What happened to BLM? People ignored them, game over. Same with "cultural appropriation" - also dead.
(This isn't an invitation to start a 15 page long debate trawling tbrough obscure university sites, twitter posts and random blogs for evidence to the contrary, I cba engaging in that, if you can't find a mainstream source for any of this don't bother as nobody reads those crap little microsites other than the idiots they are written for)
Just look at the OP, is the BBC website not mainstream?
BLM is still alive and well as is "cultural appropriation" FWIW.
edit - in fact it is nearly Halloween, I can almost guarantee that some mainstream news sites will have a cultural appropriation story to report on at the end of the month.
