We got here by ignoring the Scriptures when the say to be Holy as the Lord is Holy. For HE says "Do not commit Adultery" Deuteronomy 5 and to "Abstain from fornication" 1 Thessalonians 4:3 . Why do we ignore the scripture "Thou shalt not lie with mankind, as with womankind: it is abomination to the Lord. " Leviticus 18:22. No Homosexual will enter the Kingdom of God (1 Corinthians 6:9).
Do we think God will leave us alone, when He has already dealt with the Ancient Empires of Rome, Egypt and Babylon?
The only argument against what you wrote is that “adultery and fornication” imply sexual relations betweena man and a woman outside of Holy Matrimony. Sodomy is the proper term for physical relations of individuals of the same sex with those parts of the body designed for the elimination of bodily waste.
