I do not wish to spoil your enjoyment of this thread by making irrelevant and negative remarks, though I did make an observation that is both amusing and descriptive of how people have approached this topic. My remark has more to do with the method that people have used rather than the conclusions they arrived at.
The method is this: My friend, family member or an SO is an INFJ and he has this quality that I don't like. Therefore I will assume that this is how INFJs are, and on the basis of this I can say why somebody should hate an INFJ.
Some of you will say that you know more than one INFJ and spent a lot of time observing them. Exactly how many did you observe? Ten? Twenty? One-hundred? Where did you observe them? In your local town? In your state? How do you know that the qualities you observed are to be attributed to the person's type rather than their personal idiosyncrasies or their culture? Your claims would be plausible if you observed thousands of people of this type from a variety of different cultures and they all exhibited the same behaviors, but I don't think any of you have done this.
Moreover, what exactly do you think a type is other than some vague and inconsistent characteristics you read about types in online profiles and Keirsey's book? Have you done your homework? Have you thought about what exactly a type is or have you just opened some online page where it says INFJs are exceptionally creative, reserved, thin-skinned as well as fastidious and have gone on to assume that every person who fits this description is an INFJ?
Just because your conclusions are poorly supported and frequently wrong altogether does not mean that you have to stop making them. After all, the pursuit of truth is not for everybody and there is such a thing as a useful illusion, or ideas that are false yet benefit us somehow. So I am all in support of your right to be able to say something that is completely preposterous without worrying about being censored. However, since you get the right to say what you please, I reserve such a prerogative as well and therefore wish to point out where you've gone wrong. Regard my post as purely informative rather than as a set of commands with regard to what you should do or how you should believe.
