People should be treated fairly, under the law.
But, if you don’t believe in gay marriage, then destroy the law and licensing aspect of it by marrying in the church or doing it the old fashioned way by declaring you are married.
Eventually, if heterosexuals refuse to marry under the license of the state and refuse marriage tax benefits, then the system itself will implode.
That is a heck of an if, “if” people would just quit caring if their marriage is legal, then “the system will implode”.
Good luck selling that one to military families.
