It’s hard to put the peel back on the onion once it’s off. What do you tell all the “married” same sex couples? They are no longer married? The state should not be involved in marriages. It’s a church function. I can understand civil unions for purposes of contracts and ownership and stuff like that. Other than that it’s not the government’s business.
The only consolation is that same-sex relationships often last only as long as the next social gathering, when more fresh meat is offered. That, or they die much earlier from one or more of the many diseases they are prone to.
Again, who will enforce the vows of marriage in a "marriage-less" government? The government must recognize marriage, not regulate it. Otherwise, social anarchy would reign. There is nothing wrong with the government recognizing and recording the incidence of marriage because government will often, inevitably have to intervene in an officiating role when marriages either fail, have problems, or resultant children are involved. Partners in a marriage seldom die simultaneously, and the issues arising out of this event are myriad.
