As a member of the Black and Asian community (and others), first I'd like to say. What? Since when did Black people (en masse) begin assigning any manner of blame to the Jewish community as the "real enemies?" Aside from a one particular prominent rap artist and one very fringe religious group, no one I know or any of the Black online communities I frequent have ever said such. If there was a newsletter, I sure as hell didn't get it.
Regarding the Black on Asian violence we saw in the US. It was and is a damned shame. Again, as a member of those communities, it hurts. However, I know I walk the fine line of whataboutism here, but I have to make it known. The increase in Asian hate was not led by Black Americans (but the reporting of it sure as hell made it look that way). I'll leave it as an exercise to the reader to determine which group was the number one culprit of such vile acts -- from simple assault to mass murder. Regardless, no matter the culprit, any act of violence based on race is absolutely and utterly reprehensible.
We don't need a designated "bad guy" in order to address these horrible events. We all need to do better.
[Edit] I seemed to have ruffled some feathers here.
