You're half correct. However it comes directly from the rabbi's themselves who are often ultra-liberal. Not all rabbi's think the same but its the concerted effort of the Jewish clergy to keep the flock from assimilation. This is why most Jews always like that oddly shaped peg that almost fits but never does.

The Clergy of the Jews also informs them of how to vote and whom to vote for as well. We are often told that "most famous jews are agnostic/atheistic" but is that the truth or are the goym "told" that truth because the Rabbi tells the flock to not let it out of the bag.
