I think the term Zionist might even be more murky. People often equate it with the Jewish religion/people while in fact (to me at least) they are hardcore fanatics.
I have Jewish friends, the loving hippy kind, which is miles away from the psychopath nazis Zionism entails.
I have to admit, I use the term too while I know I have to be careful with it. It's just because of a lack for a better term.
Tbh, I don't know if people like the Schiffs and Rothschilds even care about ideology like Zionism other than money and power. (although it wouldn't surprise me if the actually worship the devil)
