When was the definition of marriage in dispute in America, or open to debate, and when was the definition not enforced?
Also, just how does Allah define marriage, and does he speak for homosexual churches, and the FLDS as well?
Once the government had expanded the scope of its powers enough that members of the government, particularly in the courts, felt that they could, by judicial fiat, re-define a fundamental concept of humanity.
Do you really think that the courts in the less intrusive federal government we had in the earlier years of our nation's history would have ever even dreamed of trying to redefine marriage?
