You misunderstand.

No Neverender, only you misunderstand. The term partial birth abortion was made up by crazy anti-abortion activists, it’s not a medial term. Third trimester abortions are exceedingly rare, and only happen in cases of extreme need, either to save the mother’s life, or because the baby has no chance of living or of living without extreme unrelievable pain and suffering and no chance of any quality of life.

It’s a red herring issue, created and publicized to erode the availability and legal rights to abortion at the mother’s discretion and desire earlier in pregnancy.
