I'm sure you're aware that he doesn't support, nor condone that. He has made inroads with the NYC Jewish community, as evident by the large vote totals in the primary. Use some empathy and reasoning, it will go a long way with your communicating.

He's not nor does he care. His bio is literally ranting about immigrants. He's a typical maga that doesn't like Muslims, and doesn't like anyone left of him

There's a very solid chance he doesn't care for Jewish people, he just wants to use them as a cudgel for his own bigotry

No he hasn’t rejected the Global Intifada, he supports Hamas even after Oct 23 massacre
