Actually, more like disavowed. The post-Zionists like Levy think they are the legitimate heirs to Zionism, but when you examine their morally repugnant views, it becomes obvious that this ugly creature was not borne of Zionism, but rather utterly self-centered arrogance. The claims of post-Zionists about wanting only the best for the nation are totally disingenuous. They don't really care about Israel, and certainly not about peace, but rather preventing the emergence of a state that is truly Jewish, for Judaism is a threat to the post-Zionists and their hyper-secular world view. Leaving the Territories and dismantling settlements is, for the p-Z's, not about peace-making or rectifying wrongs, but about doing anything and everything to undermine the symbols of non-post-Zionist Zionism, i.e. real Zionism, which is not ashamed of its Jewish dimension.
