I hope you are a MinorityRepublican.
As clearly taught in the Bible, God made man and women distinctively different yet uniquely compatible and complementary, and only joined them together in marriage - as the Lord Jesus Himself specified (Mt. 19:4–6) - and only condemned homosexual relations wherever they are manifestly dealt with.
Yet there is still room at the cross for all who will come to God in repentance and faith, and trust in the Divine Son of God sent by the Father, the risen Lord Jesus, to save them on His account, by His sinless shed blood, and thus be baptized and live for Him. (Acts 10:36-47) Thanks be to God.
It'll be an interesting issue but I bet if it comes up in the Senate, maybe you have 10 Republican Senators who would vote against it right now. Most Republicans see the issue as a loser so it's not worth fighting over.
Personally, I think it should be up to the states because that's what we have the 10th amendment for.
