Culture and identity are being erased across the board in all groups. I guarantee most secular Jews are first or second generation and the bonds their grandparents made still have strong effects. Like a fraternity.That might be applicable to religious Jews but Jews that keep secular like myself are no more cohesive than any other group. I think a lot of the hate just comes from ignorance, I’ve had someone ask me if Jews believe in Jesus. Truth be told the difference between Jews and Christians is quite small.
