> The typical argument against teen pregnancy is that it limits the life options for the mother, whereas you're arguing that the having these children represents harm towards the children.

I just googled "why is teen pregnancy bad" and every one of the relevant pages mentioned harms to children. And it seems pretty weird to me that you are so eager to sweep aside the harms to them. Those same teens could have children later and everybody would be better off.

> You're implicitly arguing that non-existence is preferable for the children.

I am not, and that is an absolutely wild think to take from it. It's akin to the kooky arguments of anti-contraception types and frustrated would-be grandparents that not having a child is basically equivalent to murder.
