Are you saying that the government should recognize any marriage which any church decides is a marriage? Then anyone could found a new church and solemnize even the most outlandish marriages.
Or are you saying that the government should not recognize any marriage? Seeing as how the concept of marriage is woven into the fabric of so many legitimate laws, that would require a major revision of much of our legislation.

Or maybe just get the federal government out of the marriage recognition business, too since it has no constitutional authority to grant any favor or benefit in the institution.
