WRT to your questions, the main thing I have to say is that anything which is an abomination to God is an abomination to me, but all that I may do is hate the sin, I must love the sinner.
WRT to the laws, the Scriptures are rather clear that He will remove His protection and blessing from the nation that turns its back on Him. The U.S. was founded on Judeo/Christian moral absolutes. Giving them up will have dire consequences.
OTOH, how far the law can and should go to mandate moral absolutes, I cannot say. But we the Christians ought to pray earnestly for a national spiritual revival.
My two cents...
I have for many that I know and continue to seek guidance. I will join you in this prayer tonight. Good to see you again. Warm hugs.
