It has always seemed to me that, in the case of sexual orientation, both view points are right, in this argument. I kind of see gender confusion... or disharmony, if that comes off better, as the underlying cause of homosexuality.

In some people, nature makes enough of a difference in their orientation to "make them" what they are, so they end up orienting opposite to the norm. I've seen enough obviously gay kids to believe it.

I also believe that upbringing can have enough to do with a child's orientation. Pretty sure I've seen that too.

So, yes. The answer is Yes.
