I think its can be either - genetic or cultural.
Look at prior societies in which homosexuality was pretty much common. The ancient Greeks, the Turks, the Imperial Romans, etc. It COULDN’T have been genetic in those societies as it was rare BEFORE it became common and became rare afterwards - the cultural factor here.
On the other hand, we ALL know people we had in elementary school and high school who were, “different”. Some studies have been done to indicate there ARE differences in brain wave patterns of SOME homosexuals.

My world view is that man is a fallen, sinful creature. Left unchecked to his own devices he will sink to low levels of degeneration - as was the case with Romans and Greeks. As children of Adam, we are ALL born with a degenerate nature that makes us prone to sin and perversion. Does that give us an excuse to do so...no it does not.
I don't buy the contrived "evidence" that just because someone seems "different" early in life, that that marks them as homosexual. It's used more as an excuse by the homo-activists. Sure, something that stands out can mean an underlying pathology exists, or that some factor at home or in the family is corrupting development, but homosexuality in these instances seems more like a symptom of a deeper problem.
The complexity of humans, especially fallen humans, is truly unfathomable, and the pat, shallow, pedestrian answers offered by activist homosexuals should be an insult to any thinking person.
They're disease-ridden whackjobs! Some whackjobs are "born that way", some get that way.
What studies? I know of none.
