Sliding to the Right or turning to the Left?

I'm confused.

A new book by one professor claims that Judaism is Sliding to the Right.

A new article by another professor claims that Jews are turning sharply to the left.

Which one is correct? In theory both can be right. Orthodox Jews can be moving in one direction and liberal Jews can be moving in another.

But then that means that the Jewish people is being torn apart. Alarming if true.
