One of my friends, who's been with his partner for over 20 years and is the salt of the earth, was rejected by his own family on the basis of that "Scriptural truth".
I've seen firsthand what damage is caused by this "Scriptural truth".
And you can forgive me for calling it by its rightful name.
Sorry, friend, but God isn't a bigot.
What human beings do to ruin relationships because someone is doing something they don't approve of, is an entirely different thing than being obedient to all of Scripture, and treating sinners (that would be everyone) with love, but still recognizing the truth of the sin.
What you continue to do (as do all who reject God's truth) is that you look at sinful human beings for your evidence, and not at the Word of God, itself, God's character, and the person of Jesus Christ.
As long as you look at sinners to guide your opinions, you will believe what you feel like believing, as you reject Scriptural truth.
Fix your eyes on Jesus, and all this confusion and anger will end.
