One of the problems is that the media throws out conservatives, Buchanan comes to mind, that say the same thing. Anti-war, anti-Bush, but a political conservative. The current Gibson dust up, he's described as a conservative. Anti-war, anti-Bush, but a conservative none the less. Not everyone pays attention beyond the evening news, lot's don't get that far.
The Democratic Party is seems more hospitable to knuckledragging antisemites. Pat Buchanan never goes further than saying, in effect, Hezbollah may be repulsive, but we don't have a dog in that fight.
I tend to be a "liberitarian isolationst" to the extent that such a thing isn't a contradiction in terms. (If "undocumented workers" carried their own weight, I'd be a member of the open borders crowd. )
Growing up in Queens, the local deli man and his wife had numbers tatooed on their arms. I can still feel the frission of revulsion that shot through me when my mother explained what it meant (I was about seven) and I've always been an reflexive antiantisemite since. (I guess I'm reflexively anti racist, not because I'm such a good person, but I find racism silly. I judge people as individuals rather than as representives of ethnic or racial groups.)
I would say Pat's a populist/isolationist and Mel, well he's just f.....up!
