This I agree with "anyone with some academic experience in social sciences will tell you that all the ideologies emerge and function within their historical contexts and goals and later on are rewritten according to the needs of present day." But it fits anti-semitism much more comprehensively than it does Zionism. The specific point you mention "claims that Zionist movement leaders tried to advance the establishment of the Nazi regime in the 1930`s, in hopes that the tension between the Germans and the Jews would lead to massive immigration to Palestine". The extent of this, I do not know, but I've often heard anti-Zionists bring it up without any sense of context. Zionists in Europe in the 30's would talk to anyone who would listen. That doesn't mean that powerful Zionists conspired with the Nazi's. This is, in certain circles a common accusation. It becomes holocaust denile when it is suggested that Jews, manipulated the Nazis into genocide.
