First of all, in response to this person, I can’t help but laugh at you

I love seeing bigots get all upset when they don’t get their way.
To the original poster, what I’m inferring from your post, and correct me if I’m wrong, is that at the end of the day a man cannot truly be a mother and vice versa, and that these are both essential factors in raising a healthy child, (and this is where I’m really inferring, so forgive me if I’m mistaken), therefore, one problem with allowing gay marriage is that if a child were to be adopted by a gay married couple it would not be good for the child because he or she is not fully getting the twofold aspects of parenting that a child needs.
If that is what you’re saying, I would respond by saying show me some legitimate data or studies that show that without a true mother figure and a true father figure, the child’s upbringing will not be good, or as good as it could be, etc…
Also,
If my inference is correct, I would say, should a Defax van come take away a child from its family if one of the child’s straight parents happens to die?
If I’m totally wrong with my inference, please correct me.
