Two women could have children from their own DNA with a little genetic engineering or just cloning. Plenty of heterosexual coupples can't have children do you want to forbid them getting married? How about if they decide not to can they get married?
PS: I honestly just get creeped out when people start talking about labels as if a word by it's self means something.
Yeah. I'm all about the 'traditional marriage' myself. You know, where my lord's regent picks my wife from one of the other serf's, pays her father a small dowry, lets my lord enact Prima Nocte, and then unloads her onto me, where she's my property to do what I wish with.
Ok, that's creepy, but if they are 30 and 50 what's the problem? My point is just because I don't like something does not mean I get to stop people who are not hurting me from doing it.
There was some story about people who where both adopted got married and then found out they where siblings. And yea it's creepy, but while I would be ok forbidding them from having children (for the public good) I don't see the value in forcing them to break up. And, even forbidding something on genetic grounds becomes a slippery slope problem because it's one step from their to sterilizing people.
