“I was born this way” is no longer the thinking w/r/t homosexuality. It was a short-lasting trope actually, probably more political than scientific in origin. Modern theories leave some room for genetics but nothing like what the public came to believe back in the 2000s and early 2010s.

There’s a lot more to being born a certain way than genetics though. For example the pseudorandom way neuronal cell interconnections are initially established. The dynamics of the way cells divide and specialise and how organ structures form in an embryo is a long way from being predictable or well understood in terms of the variation it might introduce.

Yeah even gamete epigenetics is not particularly explored at this point outside of plants and a handful of tiny organisms.

It's certainly not the same argument it was, but there are still quite a few theories that involve genetics, epigenetics, or familial gene competition.

For instance, that certain gene combinations that may present advantages for not the individual, but the individuals mother, grandparents, or other family members.
