That’s like blaming the gun. There is no evil in IVF but like a gun it can be misused by evil people. Homosexuall couples should not be able to adopt via IVF or any other way.
One might say this case disproves that. IVF separates the conception of a human child from the marital act of two parents. To do so reduces the child to a commodity, created to be bought and sold to the highest bidder, no matter how perverted they may be. If the child is not perfect, like any other commodity you dispose of it. Every child has a right to be born to it's own parents, but not everyone has the right to have a child at any cost, especially to the point of creating one in a petri dish. It also involves the murder of the other children artificially conceived at the same time --a cruel death sentence for simply not being "the chosen one".
