Then keep looking. To be sure, it is not happening overnight, people have a hard time shaking off a lifetime of beliefs. It's not easy to realize that you have been wrong for many years. And it's mostly non-religious, secular jews who are hanging on to the Democratic party, covering their ears and pretending they don't hear the rising chorus of jew hate. I left, and personally know other Jews who have left as well. Then there are people who are somewhat well known who have decamped; actor Ron Silver comes to mind. And, of course, my particular hero: David Horowitz. If the Dem party continues down this road, the Jewish Democrat will go the way of the Dodo.
I hope you are right and only wonder at it's taking so long.
