"You are the one who claims homosexuality is genetic so it is you who must prove it."
I REPEAT
"I offered two mechanisms,
the first is hereditary
the second is not."
It takes many years of observation & experimentation for anything to be established in the Scientific lexicon. What I offered was a statement, and then explicated two mechanisms that could account for my statement. Don't expect me to go rushing back into the lab any time soon.
If you can provide a citation to a scientific review of the current state of play in this field, I'll be grateful, that way we can both enrich ourselves with what the experts have to say on the topic.
