That is the reason: they hate Jews most of all.
Jews (and their Christian brethren) carry God’s message ( about Himself, which leftists correctly perceive as in the way of their own desires for supreme ruling status) (And the “Bible thumpers” also carry God’s moral law, which definitely gets in the way of leftists’ degenerate “lifestyles.”). The leftists’ solution is simple : marginalize, disempower, trivialize, and if possible disarm and kill the Christians and Jews. Ps: they often attack the Jews first because they correctly read history that the smaller-in-number Jews gave birth anyway to the larger, more pervasive Church - but even Hitler subjugated, marginalized, disempowered, and was beginning to round up the more- numerous Christians.
“That is the reason: they hate Jews most of all.”
And, if you analyze voting demographics in NYC, you will also realize that most NYC Jews ALSO hate Jews most of all.
