These people have been brainwashed by lying right wing propaganda for decades. Surely that is a big factor.
The propaganda used by facists to push their antisemitism has a lot in common with modern right wing xenophobic propaganda.
Absolutely. The Trump presidency wouldn't have been possible w/o the tireless decades old efforts of right wing propagandists to crazify the Repub base & all of America.
Unintended consequences don't matter so long as they keep voting for the Party of trickle down flimflammery. As that has become more difficult they've responded with even more craziness culminating in Trump.
