Hey, lighten up. The kid said a couple of good things about the people who raised him. That's a good thing. The unwritten rule in sports is you never say anything negative about someone's mother for any reason....
He only has ONE mother, the other woman is just the woman who plays with his mother's vagina to orgasm.
Does he even come from a state that allows sex partner adoptions? 27 states restrict homosexual sex partner adoptions if not outlaw it. This assumes his mother's carpet muncher even bothered to go through the legal process.
Tradition is about protecting mother and tradition, not about protecting deviant fetishes. If his mother liked having sex with animals, is that verbotten too?
