"Self-hatred"?
Paul Mirengoff at the estimable Power Line (you've heard of 'em?) thinks left-wing blame-America-first-ism is "self-hating". He's mistaken. They don't hate themselves; they hate America. They feel no particular connection between the two. Nancy Pelosi speaks of the United States in the third person. When these people sell the country out to curry favor with idiots who despise them, they don't think any more of it than they would of selling, say, their mothers.
