I want one good reason that being gay is ok

You can refuse to believe anything you want to without affecting reality all that much. Evidence keeps mounting up that many gay people are, in fact, "born that way." It doesn't appear to be a "choice" to be attracted to people of the same sex. Of course, it is (most of the time, we hope) a choice to have sex with another person. But that's also a heterosexual choice that the apostle Paul, at least, seemed to think was not the best option - "better to marry than to burn with desire" or words to that effect.

Bullshit, Buz. And unsupported bullshit at that.

Being straight, and having straight sex are different.The first one you cannot help, the second you can.
Actually the first one you can help, with the help of God.Right?

That's what he just told you, Riverrat!

I guess you do. You haven't addressed it in 400+ posts now.

It's an extrapolation from the story of Onan in Genesis 38. He was told by Judah to go impregnate his dead (smitten by JHWH) brother, but instead he "spilled his seed upon the ground." So he, too, was smitten plumb to death.
The passage reads like Onan was practicing coitus interruptus and his failure to fertilize his sister-in-law was what irritated the Big Guy, but preachers of 100+ years ago claimed that any sort of spillage was smitable. (Usually, you just went blind and grew hair on your palms for whackin' it in the 1800's - getting smote had somehow become diluted.)
