You're right. The difference between McCain & the leftist Democrats is this. McCain thinks America was an evil, diabolical place until the 1960s. But thanks to all those liberal movements during that decade, America became a tolerable place to live. We still have to do more (amnesty, for example), but we're on the path to multicultural utopia. We should continue down that path, and also invade some other countries if that's what's necessary to make them into “multicultural democracies” just like us.
The Democrats think America is still an evil, pathetic place. Yes, the sixties radicals helped correct some of the Founding Fathers’ wickedness, but really, America is just too depraved to ever be an example for anyone. We therefore should just wreck the entirety of Western Civilization as fast as possible and be done with it. We shouldn't invade other countries, or even defend ourselves.
