What does that even mean? Sperm meets egg, baby is formed. That's how gay couples do it just like straight couples. (or they adopt...just like straight couples)

Either marriage benefits society or it doesn't. If you believe heterosexual marriage benefits a society, then obviously same sex marriage affords the same benefits.
