If we won't listen to Children of SSM who will we listen to??, page-85

The difference with SSM is that it legislates away the child's right from at least one of their biological parents.
We don't as a society set out to create orphans, broken families etc.
In other countries the link between child and parent is further being diluted so that the child may not have contact with either biological parent. That is both not good for the child and society at large.
