What fueled right wingers, fathers rights, mens' rights, gun rights & teabaggers into existence?

130. The Bell Curve employed "studies and statistics", too.

But it was little more than a detailed justification for prejudice and in-group/out-group thinking.

I'm not under the impression that you wrote this book, only that you're taken by it-- as people tend to be when they read things that validate their opinions. To be clear, I don't actually disagree that much of the right-wing anger is rooted in a formerly dominant group seeing their dominance slip away. But I think it's a class thing more than a gender thing, as I've met plenty of women who could easily fit into that mold. I also don't think it's fair to lump father's rights groups in with right-wing loons.

As a side note, I don't see how your point about men in Latin countries bolsters your point-- unless you're saying that shooting sprees or Tea Party groups are just as common there, which they aren't. It would seem to support my suggestion that there's a connection between some of the groups you described and social isolation, if both the groups and the phenomenon of social isolation is more of a US thing.
