The term Jewish supremacism isn't nonexistent- factually, there are Israelis (mostly religious nationalists) who are Jewish supremacists with opinions just as disgusting as David Duke's. But the way she presented it as Israel's core goal is, obviously, as antisemitic as they come- as are people here who jump at the chance to talk about the (((lobby))). Basically all modern antisemites use Israel as the new elders of zion, and Ireland has a history of antisemitic voices.
It's one of those terms, to me, that has an entirely different meaning coming out of a non-Jew's mouth vs. a Jewish person's mouth. Similar to discussing Chicago crime rates with a black youth leader vs. a Republican Congressman from Iowa.
But every time I, a person of Jewish descent, say this, you still call me an antisemite. So practice what you preach.
