I know a homosexual man who behaves reasonably. I didn't know that he was homosexual until someone told me.
There are some of them who act like stereotypical faggots, and I don't enjoy that behavior. But it's certainly not all of them, probably not even most of them.
This sort of behavior is not "acting like the opposite gender". If a woman acts like that, it's just as obnoxious.
If a behavior is okay for one gender, but not the other, then we're really just holding one to a lower standard. If it's shit when one does it, it's shit when the other does it, too.
As for homosexuality being a mental disorder, I think that it is not. Why call it a disorder when it doesn't cause them any problems?
A depressed individual suffers and may want to kill himself. A trans gendered individual doesn't feel at home in his own body. A retard has lower intelligence than other people.
But what does a homosexual have? He just wants to stick his dick in another man. If that's a mental disorder because it doesn't lead to reproduction, then being a reasonable human who acknowledges over population is also a mental illness. So is wanting to live alone in nature away from other humans (since this prohibits reproduction). And so is not wanting to have children for any reason what so ever.
If no one had children because he was horny, but because he intellectually decided to do it, which is what homosexuals have to do, then humanity would be better off. The idiots wouldn't breed out of control like they are doing now. We could keep our numbers under control, and inseminate women with sperm as needed, instead of having idiots produce more children than they can take care of (they can't even take care of one child properly) because putting on a condom or pulling out is too difficult.
