A neoCon is a conservative who is not antiSemitic.
It's a malleable term. Given some theories, every senator who voted for the Iraq Liberation Act in 1998 could be a "neocon." Including Kerry.
That is a ridiculous comment. Was Goldwater an anti-Semite?
That's a bit too narrow. I actually am a "neo-con" -- and a Jew. But I'd hardly castigate non-neo-con conservatives as antisemites. A few I think are (i.e. Buchanan), but the overwhelming majority I think are genuinely good natured people who just don't buy neo-con teachings.
