They are deluding themselves, as always. You cannot make a moral argument in favor of abortion, which is the intentional killing of a human being who has committed no crime to justify execution.
All their verbal gymnastics only prove that they know what they are doing is evil.
Perfect summation.
Also by their actions, they set their own judgment. If they determine it's okay to murder the innocent (they aren't really people, they say), then they shouldn't gripe when they themselves are... dispatched.
God could just use their own standards and say that these abortionist folks "aren't really people", because they wantonly kill the innocent.
Besides, for every woman they ensnare (who might otherwise choose life), they score extra soul destruction points.
