The "No true Scotsman" fallacy is a device that can be used to pretend one's own side is pure as the driven snow: Was this particular Christian found out to be, for example, a terrible bigot? Why, land of Goshen! That person was clearly no real Christian! Christians love their fellow man! Thus, the rest of the group can stay happy that the menace was that not-Christian over there and he's not in the club, and the rest of them will just not act like him. In public anyway. It can also be used to deny the flaws in your absolutist argument.
If all abortions are bad, but some abortions actually would be not-bad, then those abortions are no true abortions. We've seen this a couple times just now. The not-at-all connected to anyone you would have heard of counsel for the Alliance for Defending Freedom (an Orwellian-ass name for a group trying to take folks' rights away) just yesterday wanted to pretend that maybe there was a thing that terminated a pregnancy that wasn't an abortion. And also, an anti-abortion activist claimed that if a ten-year old got an abortion that saved her life, well, that wasn't an abortion at all, was it?
Well, yes it was. It was a medical procedure or medicinal application that terminated a pregnancy--that's an abortion. If you need to end a pregnancy to save a person's life, just say so! Why the backflips? Just admit some abortions are not whatever you think the "bad" ones are!
