I have known only two Jewish people…..very liberal and both atheists (or at best agnostic)
They both see Judaism as a …well…a social club and care NOT for their religion or the people of Israel…….
I, like you, don’t understand….
Don’t confuse “Secular” Jews, with orthodox Jews...
Secular Jews are mostly Leftist Liberals more closely tied to Communist ideas...than Judiasim.
they are complete opposites.
A couple of hundred years ago, there appears of have been a schism in Judaism. Some Jews continued to be traditional Jews, while others decided to worship Socialism. The schism is not often commented upon, but is very real.
