Yepp, the main one you may know about is the Stephen Jackson incident where many NFL & NBA athletes liked a post of Desean Jackson trying to quote Hitler saying the Jews need to be exterminated. Trust me it gets worst the more you look into it.
There is more of an overarching narrative of anti-semitism amount the black community though. And the ideals of Louis Farrakhan have a lot more sway in the BLM than people are willing to admit.
The ideals of Louis Farrakhan run deep in the BLM movement.
Just look how BLM treats these two Jewish people trying to march with them.
