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.
Ah, the lines are being drawn. Israel is almost completely isolated and vilified by genuinely good natured people ...
