If there needed to be a 'requirement', we wouldn't need birth control would we?<quoted text>
The "basic essence of marriage" is a human legal matter, not a natural matter.
There are no legal "marriages” in the animal kingdom outside of human governmental law.
You are free to call your grotesque marriage whatever you want to, but you will not be defining mine or anyone else’s.
There is no requirement of intent or ability for procreation for a marriage license, we marry couples all the time and have for hundreds of years that cannot have children. Your belittling those people is not helping your case in any way at all, you are only driving more people to our side of equality and freedom.
