Several things:And yet twice as many before supported Trump? why the dichotomy? (I'm not saying your wrong... trying to understand)
OK... I',m just saying.
1. When your pool is small, small shifts in number seem more significant than they are. You could call a demographic increasing two times when it goes from one to two, even though the other ten other for the other guy.
2. If you look at the NYT exiting poll, its less than 1%. Statistically negligible.
3. Day of vote exiting polls are not a good sample selection in the best of times. But in an election where one person told their constituents to vote in person it's *especially* skewed. This polling method doesn't account for early vote, which was overwhelmingly for Biden.
4. A small minority attempting to pass in accepted society, even if it means bigotry against self and peers, is a historical phenomenon constantly repeated. Association of German National Jews - Wikipedia
It is not indicative of said minority not being persecuted.
