Not all Jews were Bolsheviks.
When the Bolsheviks took over Hungary at the end of WWI for a time they didn't treat the non Bolshevik Jews well and that is why there are so many Hungarian Jews in the United States.
how Antisemetic?
I don't think that really matters.
the Bolsheviks were criminals and wanted to control everything and everyone.
They are just anti-everybody.
