But the bonding is part of a couple...dumbass.<quoted text>
Humans form far more than "pair" bonds sir.
Your claim as to that being the basis for legal marriage to exist is ridiculous.
Legal marriage is constructed of a legal union between two adults whom find love, attraction and a willingness to enter into a legal contract together based on this.
Gays can do that and should be able to.
Simple stuff here genius. If you can't figure that out I'll bet it might take you 3 tries each morning to get the left shoe on the left foot.
