Anti-Semitism in the black community is a thing, and takes specific and often conspiratorial forms which subtly differ from white American anti-Semitism -- which is also, in case it needs saying, just as much of a thing. Meanwhile, anti-black racism among non-black Jews is also, need I even say, totally a thing. Meanwhile, there is only one demographic group that votes more consistently for Democrats in the US than Jews -- and that's black voters, who absolutely blow us out of the water, despite having a lot less reason to trust the Democratic establishment. Non-black Americans schooling black voters for not being sufficiently loyal to Democrats is like Game of Thrones scolding Sesame Street for not thinking about the needs of young viewers.
