Once a child is created it has a right to exist – as all human persons do, until natural death. That does not equate to an argument that such children should be created that way. It is not as if there were some “world of inchoate children” out there with the right to be given bodily form. In addition, many children’s lives are lost as waste by-products of the commercial operation. By the by – the church approves of GIFT but not in -vitro fertilization. Strip away all your rationalization and your argument seems to be: two people of whatever relationship or sex, or one person with the will, money and desire for a child, deserve the child they want , conceived to their specifications, by any means and whatever the other human costs. Have the guts to admit it.
