I'm surprised no one's mentioned (either the perception of or the reality of) #MeToo overreach and resulting backlash, which was BLM backlash two or three years before BLM backlash was BLM backlash. Left-wing sociocultural movements really need to start accounting for this pattern in their strategy.
I fail to see how #MeToo can be seen as anything other than a major success.
I think it was; it did shift the needle quite a bit (which BLM did too tbh, although this fact is currently not talked about much). But there was a clear point around the beginning of calendar year 2019 where it started getting perceived much more skeptically rather than moving from strength to strength.
