Laws are based on morality. But let us run with harm prevention. Why do we have seatbelt laws? Should we tell someone in their own vehicle what to do with their seatbelt if no harm is done to others?
If you ignore that the LGBT community is harmful to others then surely you won't ignore that the lifestyle is more harmful to themselves.
But anyways, you made up that standard. Just as the Communist China made up their standard. America in their foundation placed it on God.
Like it or not that doesn't imply a theocracy. It is a fact. It is what makes us American. And like it or not God's way is the best for society and each individual. I will vote and remote this because I love my neighbor and future generations. It is much bigger than selfish desires, it is the collapse of society we are trying to prevent.
So Im sorry if that doesn't sit well with sinners or the ignorant but until Christ returns we have a country to preserve and people to turn to the true morality.
Christians have no choice but to live and premote this morality.
