The real question is, 'what is the agreed upon definition of "Zionism"?' Because depending on who you ask the definitions seem to vary incredibly. For example, ask both an Israel lover and an Israel hater the definition.

I disagree that zionist = Jew. I consider myself to be a "zionist", but I am not Jewish. I was brought up to understand that a zionist is simply a person who believes the State of Israel has the right to exist peacefully side by side with their neighbors. It is people like you who add on all these other meanings to the term that make it defined as something other than what it is.

Overview
Main article: Types of Zionism
The common denominator among all modern Zionists is a claim to Palestine, a land traditionally known in Jewish writings as the Land of Israel ("Eretz Israel") as a national homeland of the Jews and as the legitimate focus for Jewish national self-determination.[40] It is based on historical ties and religious traditions linking the Jewish people to the Land of Israel.[41] Zionism does not have a uniform ideology, but has evolved in a dialogue among a plethora of ideologies: General Zionism, Religious Zionism, Labor Zionism, Revisionist Zionism, Green Zionism, etc.

So I say again, given that the term has "evolved in a dialogue among a plethora of ideologies", what is our agreed upon definition of "zionism" for purposes of this thread? I suspect we are NOT coming to this conversation from the same understanding.
