If you portray PPP as a serious person worthy of rebuttal, you've already lost. He's only serious about grifting money off peoples failures, he doesn't care whether Anisa was ackshually 100% guaranteed cheating on Ian, the humour comes from it being plausible because of their relationship dynamic. This is like Sam Hyde all over again, he doesn't understand that people can be entertainers and have a private life separate to all the blustery and buffoonery. When he turns off the stream, PPP doesn't care about Ian's life at all except maybe to chuckle to himself from time to time at what a loser he is, he's not some freak gooning to the idea of Anisa being blacked (if only because no one is gooning to Anisa).
