Wow. Great stuff.
First off, I don't consider sociology hard science. No way to really measure what is going on in families / relationships, there are too many factors to know what causes what.
Agreed. Not hard science. But I'm referring to the sequence of events. Current research says that biological factors in utero determine sexual orientation.
However studies have shown families with strong mother influences, i.e. the mom runs the house, are more likely to have children who identify as gay.
Yes! And environmental factors definitely impact the mother. But there isn't yet the degree of understanding required to state how or to what extent. So sociology (a soft science?) could help inform (maybe?). However, it doesn't change the fact that the impact on the sexual orientation of the individual happens in utero.
Also studies show that families with multiple siblings, it is more likely the youngest will be gay. They try to say this because of some worn out uterus idea. if so it may be biological. But I don't think there is strong proof of that.
I suspect have several older siblings could affect how you grow up, either you picked on or doodled after. So certainly family dynamics could explain this too.
I believe that research is converging toward identifying the chromosome responsible for sexual orientation. At one point it was thought that there was a abnormality at the gene level (X,Y) that resulted in homosexuality. Since then, they have moved away from that idea and think a separate gene is in play.
Also higher iq correlates with being gay. Is that biological, or do people with higher IQ get encouraged more to go against societal norms.
As I said, I think it is some interesting ideas, but I don't think you can really say it is biological, environmental, or a combination.
That's a really interesting question. I dont know the answer. I've read intelligence is nature/nurture. You are born with certain abilities and the in which you are raised informs the degree to which you'll reach your potential. Maybe that's the case with sexual orientation: you're born gay or straight and society shapes the extent to which you reach your "potential". Lots of research on folks repressing their sexuality. But I don't know either way.
But I think statement that it is all biological does not match current data/theories. Why is it so important to you to think it is all biological?
It's not important to me. What is important to me is a conversation on facts. And the conclusion of the scientific community is that it's biological. If tomorrow, research demonstrated that sexual orientation was determined by societal factors, or libray readings by drag queens, I'd accept that too.
Counter to your question, I have a completely sincere question (or two) of my own: Is a biological origin a difficult thing to accept? If you're not convinced by current research, what would it take to convince you?
