I believe left-wing Donkeycrats have said exactly that, on more than one occasion.
OOOOK. Is she saying that abortion supporters don't support partial birth abortion? Which ones?
More specifically, 2nd Amendment supporters believe that school shootings should be illegal (oh -- and they are). Do abortion supporters believe that partial birth abortion should be illegal?
In fact, other than that blatant dissembling, her analogy is spot on. Abortion is quite a bit like school shooting -- with the victims in both cases being completely innocent children.
