There is some debate as to the nature vs nurture argument with homosexuality.
Homosexuality is not one of the 10 commandments, so to put it in context it is a lesser sin than coveting your neighbor or dishonoring your parents, so I don't think it should receive the death penalty, but it should definitely be publicly banned, as @Easy_C says.
I know two younger women from my church who decided they were "lesbians" in their 20s. I know them very well, and they are not gay. I know one male friend, who is probably "naturally" gay. There is homosexuality present in nature, so there is some aspect of it that occurs naturally, but what we are seeing now is a much LARGER component is being triggered socially / through nurture. Does God care whether homosexuality comes from nature vs nurture? I'm not sure on an individual level, but on a societal level, the public acceptance is creating tons of more sinful homosexuality where there would otherwise be a much smaller "natural" amount in a society that didn't celebrate it.
Enforcement issues also exist with being gay or private guy acts. It's potentially hard to prove and extremely easy for authorities to abuse.
