Neither can ANY straight couple if one of them is infertile.<quoted text>
All men are created equal ends at birth.
Gay couples can't create anyone.
Does that prevent them from marrying? Should it?
Of course not, and you don't believe it, either. It makes you a bit hypocritical to apply a child-bearing standard ONLY on gay couples, and not on straight couples.
Why do you keep trying to do it, when you KNOW it's illogical?
