Homosexuals refers to people who are born with genetic disorder and sin comes through actions (you commit a sin) but not born with a sin
But gay supporters are people who see it right for people to sleep with the same gender, this is sin which was condemned by fire.
One of the biggest problems the church is facing today is that they think because Jesus died on the cross so God became another person who happens to be Jesus, this is wrong, he says he is the one who is and the one who was and the one who is to come, the same Jehovah
This confusion start with this interpretation of the son and the father
God is one, whether he appears in three forms, they call the Father, son, and the holy Spirit but is doesn't change the oneness of God otherwise we would be worshiping gods or angels.
Now should you believe that God is one, could it be the case that God made a mistake to destroy gays with fire?
Or you think God was going to look at the blood Jesus and forgive them and let them continue?
My believe is that God was demonstrating the way he hates perversion and if he changed today, then you elaborate
Note there were sins before but none of them were punished by fire here on earth
