Have you ever thought that homosexuality might be...?

It is not genetic or any disease

but if a society of abundance or excess dulls the mind.

the excess returns to one wanting to fight. , excess alcohol, traffic, etc.

You think too much. About the wrong stuff.

Homosexuals are gross

Most of the people here are ignoramuses when it comes to science, I know there are several species of frogs that have the capacity to change sex based on environmental conditions (not having enough mates)

There's the famous transformation of grasshoppers into locusts as a response to the environmental conditions.

Epigenetics is fascinating but science deniers are too stupid to know this.

Yeah, take a look at the science deniers here, xxx000au, Nineteenthly, Stunning and brave... most just repeat extremely watered down versions of "science" without understanding anything of what is going on. But the instant you try explaining what the science actually says they'll deny anything and everything scientific and just keep repeating their safe words.

Yeah, that's been proposed. Like an environmental response to overpopulation. (All genes are switched on or off by the environment. You can't extricate nature from nurture.) Species do better with more females, fewer straight males, and gay males as caretakers.

Rubbish.

For that to play out, the factor that causes homosexuality would need to be aware of the planets ability to feed us and how many people are alive.

Childish logic.

I think there are more gay people simply because there are more people in general. Its also becoming more and more accepted so less people stay in the closet.

Yes, but as far as I know it's polygenic or not related to genetics at all. I think it may be modulated by the maternal immune system.

It likely has more to do with availability than density.

If that were true there would be a LOT more gay people now. The planet has long since passed the limits of sustainability.
