Nature or Nurture? Liberal or Conservative?

An irony recently occurred to me how "political correctness," from either a conservative or a liberal perspective can affect the views one holds.

How many of the observed differences between men & women is due to socialization, and how much is innate?

Some liberals will argue that personalities differences, such as preferences for sports vs. playing with toy weapons vs. toy home appliances, playful roughhousing vs. sharing of feelings is due entirely to socialization and expectations that parents and society have for boys & girls. An infant is a blank slate.

Many conservatives on the other hand, believe that these are innate and due to cerebral and endochinogical differences between the sexes.

But when talking about sexuality, whether one is innately heterosexual or homosexual, the views are reversed. Liberals insist that sexuality is set at birth. This view is politically motivated because if sexual preference is not innate, then homosexuality can be classified as a disorder and reversed through treatment, or prevented through protecting children from influences that might cause them to become homosexual.

Many conservatives argue that sexual preference is largely due to nurture. This justifies discrimination against gays & lesbians under the guise of "protecting children." But if sexuality is innate, that makes discrimination against gays & lesbians the moral equivalent of racial discrimination.

So for Nature or Nurture, both sides of the culture war need to make up their minds? Personally I'm not emotionally invested in identifying myself as liberal or conservative, so strattle the fence. My belief is that 60-80 percent of the personality characteristics associated with gender, including sexual preference, is innate, and maybe 20-40 percent influenced by environment.
