Okay, let's say for instance, in Romans 1, Paul IS addressing Nero and his homosexual type 'wives' and the early homosexual pagan acts of the ancient Romans. Now if that were the case (and I believe it is) than what Paul wrote in Romans 1 about Nero and the early Roman pagan homosexual beliefs -- I would like to state to the church that there is every probability that speaking about Nero's male "wife" or "wives" is what got the early Christian's killed and fed to the lion's. And, possibly got Paul murdered as well.
Now if Christian's were killed for preaching this in ancient Rome, then it is unequivocally without a doubt not something that should be accepted by any Christian as anything other than sin. People got themselves killed for preaching this! So, to accept homosexuality as not sin, is like saying the Apostles were murdered for no reason, and that would just be horrible and I cannot accept that.
