Is a liberal approach to defense and foreign policy a result of hormones?

"...Women also get a boost of oxytocin, the feel-good hormone, when they speak to others, and estrogen enhances its effects. While men get this, too, testosterone blunts its effects. "This makes sense from an evolutionary point of view—men can't defend their families if they are burdened with high levels of a hormone that compels them to make friends of all they meet," says Dr. Legato, author of "Why Men Never Remember and Women Never Forget." "Thus, men in their prime with high levels of testosterone are the least likely to be interested in social exchanges and bonding to others."

****Perhaps this somewhat explains why women are predominately "liberal" and conservatives think liberals are a bit,ahem, "effeminate."***
