more to the point......
....is the question of why should we care? If marriage is a sacred estate to be entered into by only a man and a woman----great. Let it remain a sacred estate, and let us keep the sacred where it belongs, in the churches. Let us get the sacred dogma out of the legal arena--and be vigilant to keep it out.
In those churches with a different definition of marriage, let the gays wed. Non-gays should have no objection if they only consider this is the ultimate birth control---gays can't reproduce, so straights can rejoice in hitting on a zero population device to reign in the gays.
Gay marriage is a win-win situation in this view.
