My theory is that for the most part they have been raised by single mothers, and have had limited interaction with heterosexual male role models. I think that would be an interesting sociological study, if any researcher dares to entertain the idea.
I agree - it would be interesting to study the childhood’s of these incredibly confused people. It would make sense to me that single mothers would predominate - maybe many of them blaming men for their situation which rubs off on the children.
