Imagine if you are an unmarried heterosexual couple that wishes to live together. You know darn well that no matter what the state or any “church” has to say, to men can never be married, and can never have sexual relations that is not sin.
So, it would make absolutely no sense to prohibit unmarried heterosexual couples to live together.
If homosexual sex is not a sin, then there’s really not such thing as sexual sin, or it is at least very rare.
I believe that is the reason why so many people embrace the rainbow flag. They know that if homosexuality is not a sin, then probably whatever they do is not either.
Actually, as dumb as it sounds, many people actually believe the only sexual sin is to sleep with someone who is married.
