Can you describe your relationship about INTJs?
Te alpha wannabes. Nobody asked for that commonsensical Te info and yet it is offered freely and willingly, like something that makes them superior...... Oh and that tert Fi is super annoying when they turn it into a battle of "who's morally superior". Like. Nobody asked, Peter. I know you don't give a shit about humans, just animals. And by humans that includes me.
...But that's only about one vegan INTJ who exhibits all the traits of a covert narcissist that I have to deal with daily. ...And yes, I shouldn't have generalised, but I did it because it was cathartic.

(Sorry, other INTJs.)
I think with INTJs it depends on how well you get to know them and what kind of person they are. The unfortunate part of INTJs is that it's so stereotyped that a lot of 'holier than thou' people associate themselves with it.
When INTJs actually aren't assholes, though (I honestly don't care if they mistype themselves at some point, it's on them, not me, to type them, though I will probably proof the idea), they're great for offering alternative insights especially about others behaviour, and Te-Fi usually can agree on some level, assuming a degree of similarity and understanding on the way the world works. (Otherwise you go back to the first paragraph, where it becomes a battle of ego, and they're definitely going to win the ego thing because of how Ni interacts with Fi.)
Ni is pretty much Si's blind spot, and vice versa. It's about communication, and the quality of exchange offered depends on the individual.
But anyway, I seem to attract quite a few at the moment.
