And after all that mumbo jumbo pontification?<quoted text>
Actually, it's not a fact. It is a claim made by a person who is not very intelligent.
a) Marriage is a legal contract to secure certain rights and protections.
b) Procreation is neither a prerequisite for, nor a requirement of legal marriage.
c) Infertile heterosexual couples are regularly allowed to legally marry.
You seem to have great difficulty in understanding what is factual. You certainly seem to have no clue what is rational.
A ss couple is still only ever a mutually sterile, pointlessly duplicate gendered half of marriage.
