This is empirically false. While racism is an essential component of segregationist thinking, anti-Semitism is not an inherent part of anti-Zionism. This is evident in the many Jews who do not subscribe to Zionism and the anti-Semites who embrace Zionism.
Also, just because a group that subscribes to one view is predisposed to another view doesn't mean that both views are dangerous. If it turned out that 99% of convicted war criminals love apples, that wouldn't make apples dangerous.
