You only have to look at the history of abortion to see the relevancy of having a marriage amendment to the Constitution. If we had had a ban on abortion in the Constitution before 1973 those horrid men on the SC could not have made abortion legal. Same with gay marriage. If there is a ban in the Constitution some judge is not going to be able to come along and nullify marriage as being just between a man an a woman. Right now there are four states where judges have nullified amendments to state constitutions banning same sex marriage. You are right that God has sanctified marriage as between a man and a woman but the state can come along and make it very difficult to keep marriage that way in society. I for one don't want to leave my grandchildren the legacy of perversion.
The Constitution is supposed to be about government behavior, not personal behavior. The attempt to change/outlaw one form of personal behavior was thumpingly reversed in a little more than a decade. Why do you want to change the focus of the Constitution?
i am against abortion but you don't amend the constitution ever to take away rights.
Once gay marriage is legal in this country, and I believe we're fighting a losing battle against it, it is only a matter of time before we also lose true freedom of religion. That is the Evil One's ultimate goal, courtesy of gays and lesbians.
