It is true that most Jews are agnostic of atheists?

"Jew" refers to both an ethnicity and a religion. If you go back far enough you reach a point when law, religion, culture, customs, traditions, and language are all one and the same thing. There is no difference between religion and "just the way we do things." Modern people sort these things out. So yes, there are Jews who are not religious and Jews who are not observant. It is difficult to put numbers on these categories, so the best one can say is that many Jews are agnostic or atheist.

what? what does agnostic of atheists mean?? jews are not agnostic or atheistic. they believe in a monotheistic holy higher power that does have a name and identification according to them.

I think that's the most generalizations I've ever seen in two sentences. Congratulations!

What part of "Jew" is not getting through to you. Most Jews are... wait for it... Jewish.

I don't believe so.
