Jewish communties have been pushing the exact kind of dialectical hatred against whites

Translation: Jews are woke anti-white "cultural Marxists" pushing "reverse racism".

that they claim to want people to stop using against them.

Translation: antisemitism and woke stuff are literally the same

I’m deeply disinterested in giving the tiniest shit now about western Jewish populations coming to the disturbing realization that those hordes of minorities that support flooding their country don’t exactly like them too much.

Translation: I don't care about Jews recognizing antisemitism in minority populations.

I honestly have no clue which minorities he's talking about here, or if it's just some generic conflation of all non white groups.
