In fact, we are dealing with several different situations--"creating" a child from two donors or bearing one intentionally with one donor or adopting one as a lone parent. All involve the choice to parent without a partner. I would suggest there is a moral continuum here but the common thread derived from the story--lone parenting--is not the default negative. When you compare child outcomes and once you control for specific factors such as education, access to resources, and family and social connections . . . lone parents do just fine. You may not like it, and I suspect you don't, but your characterization of all lone parenting as a "catastrophe" is way over the top.
