Anti-zionism is not to be confounded with anti-semitism.
I am against the principle of Zionism, but I have nothing against their religion. A critique of Israels dealings with the Palestinians should not be viewed as anti-semitic either. Israel has engaged in actions which ought not to happen. They have endured much pain, and have been and still are under the threat of terrorism, but the way in which they have handled the situation and plight of the Palestinians cannot be excused. Same goes for the way many Palestinians go about the issue.
