his Christian apologist is an extremely stubborn, obstinate, and borderline insane presuppositionalist philoso-troll. Like other presuppers, he will shut down any conversation or argument with questions like "how do you know that?" and demands for opponents to justify their ability to reason, but with a level of antisocial animosity at least an order of magnitude higher than your average presupper. Basic-to-intermediate philosophical knowledge (and/or equal levels of trollishness) is recommended in dealing with him, but he's better off just being ignored at all costs.
