Family First: "...one of my kids were gay?", etc.
Not sure what you are getting at here, specifically. It is the privilege and obligation of every society to establish laws which encourage or discourage certain behaviours according to its aggregate morality. Like it or not, America is still a Christian society; distinctively Protestant, in fact. The social friction we are seeing in America comes as Christianity is losing its influence. This is largely due to the failure of American Christians to engage their own culture with the Gospel of Jesus Christ. In its absence, every manner of behaviour and belief is swooping in to fill the void, as people grope about for happiness and sense of purpose.
