This explains a lot

Threaten a man's masculinity and he will assume more macho attitudes, according to a study by a Cornell University researcher.
"I found that if you made men more insecure about their masculinity, they displayed more homophobic attitudes, tended to support the Iraq War more and would be more willing to purchase an SUV over another type of vehicle," said Robb Willer, a sociology doctoral candidate at Cornell. Willer is presenting his findings Aug. 15 at the American Sociological Association's 100th annual meeting in Philadelphia.
