Yes it was. Because you're advocating a single woman being a mother, period- regardless of how she has a child. Whether she adopts or chooses to have one of her own is irrelevant, especially is the moral argument if that the child will not have a father.
As Justice Alito told the peanut gallery "I can show you the facts. I can't understand them for you." A woman who chooses to have a child while single makes a decision to have a child without the benefit of a father. A woman who adopts a child while single makes a decision to care for a child who has no chance at the best case scenario.
They don't give healthy newborns to single adoptees, you know. First preference goes to married, stable, couples.
