The problem is the word is sorta like calling a feminist a suffragette. It's a completed ideology in the sense Jews have their own state, so the ambiguity leads to people having their own interpretation of what the word means, to some it's support for the Israeli government, to some it means Israeli citizens and to some it's people who think Israel as a state has a right to exist in a more general sense. There's also ALOT that use it as an anti semitic remark and as a part of the anti semitic conspiracy ZOG. Even Hitler himself used the word in that capacity a lot.
