You tried to defend your point of view unnecessarily and I'd a deju vu because of it. Lovely. lmao
Let's make this clear; I don't hate, INFPs. Well, our subject is "What things about INFP people upset INFJ people?", right? Upset means; "to make someone worried, unhappy, or angry" (source). So, what did you expect?
If I'd a purpose of expressing how I really hate INFPs then I would write a long message about why and how I beat the shit out of an INFP with a guitar but I'll skip it because it's unnecessary.
I really love the pure soul that INFPs has. And I have many other reasons for what I like about INFPs but our subject isn't what INFJs like about INFPs, is it?: Nope. If you have doubt I'll answer again: Nope. Okay? If you want answer, I'll give you your answer but of course not all truth is pleasant to know, isn't it?
