The Zionists hate real Judaism because Zionism is all about replacing Judaism with Zionism, as can be seen on the WZO’s web site and elsewhere.
The Zionists, in addition to being heretics who shmad Jews, are also influenced by and have practiced various secular philosophies like Nietzsche’s uber-mensch, which is partly why they hold so much disdain for, and acted so abominably towards, the Yemenites and others.
Does that somewhat answer your questions?
