So we can allow gay people to be spirit brothers then.Someone posted in another thread a response, which I believe was to you, that showed that native Americans had a partnership that was basically marriage that involved same sex couples. It was called spirit partner or something like that. But it is older than this nation and took place on this land. So, yes there is a "traditional" even to this land definition of marriage in which you could marry someone of the same gender.
I have no issue with banning someone who had a vasectomy from getting married.the ability to have children shouldn't matter. IF you are going to make that a qualification of getting married then anyone has had a vasectomy or such is banned from it
