Sorry to respond to something from 3 years ago but I felt that bluevideogame's argument needs to be refuted logically by an INFJ.
INFJs are extremely logical, often to a fault. The primary difference between the logic of an INTP and an INFJ is that INTPs primarily use logic (Ti) for the sake of processing abstract ideas (Ne) while INFJs tend to use it to help people and solve real-world problems (Fe). This is not to say that INTPs are less useful, as Einstein shows, or that INFJs are always good at helping people, as Hitler shows. But in general INTPs and INFJs can get along just fine as long as neither party is being irresponsible with their often extraordinary rhetorical abilities, something that both types are sadly prone to do if their Fe functions are not properly matured. The childish attempt at baiting us INFJs into banning them that bluevideogame added at the end of their initial tirade is quite frankly hilarious to me, as any person that INFJs (some of the best judges of character) deem wise enough to moderate them is almost guaranteed have the wisdom to not play into the hands of a troublemaker. It seems that bluevideogame is projecting their own negative emotions and tendency to react to things based on unfounded principle rather than fact (Fi being one of their shadow functions, most likely be projected) in an extremely childish way (as INTPs are prone to do when upset, due to their inferior Fe).
I wish bluevideogame the best of luck in developing their inferior and shadow functions and learning to appreciate all types equally.
Also, I would like to point out that every type can get emotional at times. I've seen some of the "coldest" IxTx types get hysterical when someone challenges them or reminds them of past wrongs. So please, "thinkers", don't be condescending. It doesn't help anyone.
Sincerely,
An INFJ
P.S. My dad is an INTP and we get along pretty well
