The unfortunate situation of these children will be the norm for all children of a same-sex marriage. A child of a same-sex marriage will always be deprived of either his natural mother or father. He will necessarily be raised by one party who has no blood relationship with him. He will always be deprived of either a mother or a father role model.
So I must be a devil child having spent the first three years of my life in foster homes before be adopted by two people who do not share a blood relationship with me. I have never even met my natural mother and father, and I guess that makes me a third class loser in the eyes of God.
You have it exactly backwards. The fault is with the biological parent(s) that purposely deprives a child of a relationship with one or both of his biological parents.
This is bad adult behavior and legalizing gay marriage enshrines this bad adult behavior and normalizes it.
The value in a sterile heterosexual marriage is that it follows the biological norm and can provide both a mother and father model to those such as yourself whose misfortune should not be compounded by the state deliberately encouraging even more children be created and intentionally deprived of biological relationships at the whim of the homosexual lobby.
