You seem to be denying that some people can do homosexual acts without "being born that way".<quoted text>
If we understand anything about biology and psychology, yes we can say something other than what we feel or thionk about homosexuality.
Homosexuality is something like, though a different factor, red hair or blue eyes. Not everyone has those, and most don't, but they do occur and the individual has no control over that. Yes, they can wear colored contact lenses and dye their hair a different color to cover up that condition, but they are still of that condition. Homosexuals also are homosexuals, and that is not something they can change, though, they can cover it up, if that is something they choose to do.
Sin relating to that is man's interpretation of things that man didn't understand thousands of years ago, and also man's propensity to demonize people who differ from them, in some way.
Take for instance Portia de Rossi, Ellen DeGeneres' sometime wife. Straight, and then gay, then straight again.
