Forget whether his Fi is following external norms or not. His trolling is mostly harmless either way. It's not a Fi issue. It's his style of trolling you should pay attention to, not the idea of trolling. The subjects are concrete and delivered through lackadaisical one-liners. Belittling threads about Asian women, calling INFPs emo, sex jokes that aren't funny enough for most to reply to. It's all too obvious and direct. It could just be some elaborate N scheme where he's specifically channeling something that seems more like conventional trolling. In which case, he's a genius. That's why I asked to keep it real then. If he really is just hiding something, then drop the act already and be the ENFP genius he is. We can never have enough of those.
