The path to the destruction of marriage has its origins in Lawrence, a brief stop in a liberal New England State for a majority of 1 oligarch to redefine marriage and straight through to the full faith and credit clause.
You know it, I know it and the proponents of homosexual "marriage" know it. Of course, should they succeed there will be unintended consequences because every adult will be able to exercise there new found "right to marriage".
It can be stopped but I'm not optimistic about it. I say that knowing that we diverge on "homosexual" marriage.
