Are you trolling? It would seem obvious that such things are distributed exactly the same no matter what ones social status or ethnic background is. It would be very surprising if it wasn't.
Sickle cell, lupus, hypertension, IQ, diabetes, etc etc are all not distributed evenly across race or sex. Also, environmental factors and epigenetics interact in complex ways. I would not be at all surprised that there’s a prevalence difference among racial or social groups.
You’re making an argument that nature is everything when it comes to one’s LGBT status and nurture means nothing, but there’s mountains of evidence to show this is not the case.
If you want to tell me that it’s JUST A COINKYDINK that so many female movie stars have male children that JUST SO HAPPEN to be gender dysphoric, your “nature means everything and nurture means nothing” philosophy on LGBT status seems incredibly far-fetched.
Your labeling my substantive comments “unsubstantive” is really really weird to me.
