I once saw someone online arguing against the popular opinion that John Lennon may have been an INFP. Their main point: INFPs are nice, some of the nicest people around, actually, whereas John Lennon was not nice at all, but was in fact well known for his outspoken rudeness and venomous sarcasm.
Lennon aside, here’s the axe I’ve come to grind: INFPs are not always nice. They are characterized above all by introverted feeling (Fi), which can quite often manifest itself as stubborn, blunt, or harsh, actually. Yeah, most INFPs are fairly low-key and chill; I’ll give you that. But rub us the wrong way, violate our cherished values, and we can lash back with acidic sting. Most people I know think of me as pleasant and kind, but those who stick around longer will see clearly that I’m a fighter too. It’s not a contradiction. Kindness matters to me, and so do other things, and I’ll fight for what matters.
