Fred's proposal is that NO State would have to accept the 'marriage' of homosexuals from another State that had legalized it. He thinks that since marriage laws are regulated by States, that the citizens in those States should be the ones voting on those laws, but that they shouldn't have to be affected by those passed by other States. Since the Full Faith and Credit Clause can be changed by a vote of Congress, rather than having to go through an entire amendment process, that could be put into effect immediately. Fred also wants to bar Federal Judges from messing with the decisions of a States' citizens on the matter.
So if a majority of the voters of New York State decided to allow homosexual 'marriage', and the voters of Pennsylvania did not, the Commonwealth of PA wouldn't have to recognize the 'marriage' of homosexuals from NY.
Yes, but for federal purposes, such as taxes, SS benefits, etc, you better believe that it makes a difference whether or not the Federal Gov’t recognizes those state’s “marriages”.
