> we literally are discovering the genetic linkages to being gay
Well you should have read your article, which says: "With multiple gene candidates being linked to homosexuality, it seemed highly unlikely that a single “gay” gene exists."
Intelligence is determined at 80% by genetics, and polygenic. All of this says that there can be a predisposition toward homosexual tendencies ("gay" is related to american homosexual culture and is a prime example of cultural imperialism), however no one is "born" homosexual. Some people with the related genes may end up becoming so, others may mary women, some may just remain alone. This is a strange, calvinist projection on human existence. Would you say that people are born criminal too? There are genes for this as well. Or let's talk about race? So yeah, sorry, this is quack science.
> we've seen more openness to teenage experimentation
This sounds really like what an enabler would say to help sexual predators targeting young people. Teen years are not a good time to "experiment" too much things in sexuality (doesn't mean it's not possible to have sex), as consequences are long-lasting and they are very easily influenced and vulnerable.
> We haven't seen a significant shift in adults that claim that they are gay in polls.
Given that "gay" is the number one thing being advertised and promoted in the US lately, especially at the vulnerable youth, yes that's not very surprising. But I think we're past self-determination now anyway, and more in some kind of weird propaganda. Same goes with transgenderism, with devastating effects (castration of fertile people among others). The US has also currently a mental health crisis, with no sign of stopping, so "data" currently shows that your remedy is either ineffective, or destructive.
Anyway, I'm not suprised here to see the crossroads between gay, porn and pedophilia. The connection is documented and quite old actually: https://sci-hub.se/https://www.tandfonline.com/doi/abs/10.13...
All of this disgusting thread makes me pretty happy to live away from the US to be honest.
