I understand your point re Romans 1:26, but in that same verse Paul specifically says, "changed the natural use, i.e., the act, and in 1:27 he refers to the unnatural lust.
And that is my point. The act, and lust connected with homosexuality, is clearly condemned.
But just as heterosexual men have a natural urge to get together with receptive women, the act of adultery, and the lust of fantasizing, are condemned. Being heterosexual is not condemned. Acting improperly is.
If you take away the same sex lust then, by definition, you no longer have a homosexual.
The earth, everything in it and everything on it is condemned. Repentance and turning from sin is the only answer. Does that mean sinners never stumble? No. But it does mean that the forgiven pick themselves up and try again. The idea is to become more like Christ. It is referred to as “putting on the mind of Christ”. It means to turn from sinful thoughts and actions. That would include being improperly attracted to same sex people.
