You have a deep mental illness. In fact, I think that to your core, you're one of three things:
1. An incredible moron incapable of questioning even basic premises put toward you by other people; one who simply cannot think critically and therefore a person only useful for menial tasks that don't require thought
2. An evil, evil fucktard incapable of love or tolerance or,
3. Someone so young that you truly don't even understand what you're saying.
I'll start by completely ripping apart your logic.
STATEMENT A: "There's a genetic issue that causes "gayness""
STATEMENT B: "Also, it might be the result of sexual abuse while the "gay" was a child, or a female-less environment for a long duration ( while in the army, for example). "
Are you saying that sexual abuse modifies ones genome? Either it's a genetic thing or it's not a genetic thing. As someone who has studied advanced genetics, I'll tell you that people are not turned gay during their life.

There's an article about it. In particular:
"The evidence, they conclude, is that people are born with their sexuality defined, and it is not the result of their relationships with other people in their early life, as had been previously thought."
But, lets go further than that:
"Some DNA sequences must be female for a male to be gay."
You're an amazing geneticist. What an incredible breakthrough. I had no idea that sequences of bases could have gender. Does guanine have a penis? Does cytosine have a vagina? It's pretty amazing that you've discovered this. Or maybe I misunderstand, is it certain lengths of sequences? How do base pairs have hormones? Usually gender is related to sexuality. How do base pairs fuck? Can base pairs be gay? If so, how do you explain THAT?
You end your post with "Those are just facts."
They aren't. You have no facts. You have only pathetic, hurtful musings. Here's how things actually are:
1. Gay people are born gay. It's from a combination of genes and hormones while in the womb. Not afterwards. Even if they weren't, it wouldn't matter because there's no "wrong" sexual orientation. No inferior sexual orientation. No superior sexual orientation.
2. Gay people are 100% normal. And common. My sister is gay, she's not abnormal. She's no more mentally ill than I am and she's a whole hell of a lot less mentally ill than you are.
3. There's no "genetic issue" because being gay isn't wrong and so there's no issue. Just a genetic difference.
4. Sexual abuse creates fucked up people but it doesn't change sexual orientation. It might lead to a person desiring to experiment with other people (maybe same or opposite gendered people) but it won't change sexual orientation. If it did, it would account for an absurdly minute percentage of the gay population.
5. If you still believe gender is binary (which I don't) then a gay man is still 100% man. Not 50%. Men have two different chromosomes, women have two of the same. A gay man still has two different chromosomes and is still, therefore 100% man.
Do some research.
