Taking marriage out of the hands of the government is not destroying marriage, it’s protecting it and putting it back into the proper venue - namely religion.
Agree, think about it from a limited government mindset. A "license" to get married? I would not think we should need a license to get married from any government entity state or local.
Marriage is not just a religious institution. It is our most fundamental and important civic, governmental, and economic institution.
That’s why Marx knew that it had to be destroyed for communism to prevail.
