i think it's more apparent what ESTjs don't like about INFps.. I think INFps tend to go with the flow more than not so they're less likely to be concerned with what's wrong with other people, ime... they might be angry about culture or something, though. But this conflict pair is what i'm most interested in hearing about. I can't see anyone hating INFps...

I have not noticed an ESTj INFp pair in real life, but I could see an INFp just reacting to an Ni polr.. like "dude needs to chill out" or something like that.. like "why get your panties in a bunch when it's not gonna turn out like that, why plan for every single thing that could go wrong, why does he care that everything is not just so"
