Here's why, and I could be wrong: Neocons, at least as far as what I know of them, seem to stand for big government initiatives and increased government powers when it suits their purposes. Now, you can be "against" big government and still be a-okay with the Jews, can you not?
Like a poster downthread, when I hear neocon, rightly or wrongly, I think of Rove, GWB, and compassionate conservatism. And that reeks to me of Big Government, just of a different flavor than that of the progressives. I don't believe big we can Big Government our way out of our current problems, no matter what its flavor.
the reason I believe “anti-Semite/anti-Israel/etc” is the right label is that when examples are given of “Neocons”, they are almost always Jews; Kristol, Krauthammer, Perle, Feith, Wolfowitz - and (apart from Kristol sometimes) they usually MOST OFTEN comment or are involved with FOREIGN affairs. In fact I cannot think of a name COMMONLY identified as a Neocon that is NOT a Jew. Rove and GWB are not the names commonly used when referring specifically to Neocons other than to note that Rove and GWB were heavily influenced by the Neocons (there’s the Jews running everything behind the scenes again)
