You can't see how gay marriage would have impact upon our social/political system?
No. It would have none. If you care to point out what it would do to the social/political system be my guest. Before you are the one who looks stupid on the matter, bear in mind that for the best part of thirty years homos have openly lived in partnerships. The only thing different between living in sin and marriage is the certificate itself. My life has not been affected one iota by gay people being in partnerships. If yours have, I'd love to know how...
