I wouldn't vote for Carson.. because of things like this. Being religious is fine. But don't bring it into politics.
What you fail to see is that SECULARISM then replaces GOD. Otherwise, bakers, hotel owners, and photographers wouldn't be forced to accept standards that are not Christian but Secular AND face "Governmentally" imposed consequences.... SO, one is either stuck with regard for GOD or in fear of the SUPREME LAW of the land as so imposed by LAWYERS AND POLITICIANS!
I find GOD so much more understanding.
