> tends to fall into the "slipper slope" fallacy territory a lot of the time it's rolled out
Yeah, and the "that's a 'slippery slope' fallacy" rebuttal is often addressing something that is an actual slippery slope a lot of the time it's rolled out. Pointing out a slippery slope by itself isn't proof that the thing in question isn't real or isn't bad. Slippery slopes are real, and are quite often bad.
