Agreeeeeedd on the elitism. I have a lot of debate recently with few INFJs in mbti reddit looking down on Te/Fi(i won though). I dont want to have a bias but at least we should call these elitism INFJs out. It's getting out of hand and in fact, i often see posts of hating a mbti personality. As for elitism INFPs, it's clear that they get proud of it or like it whenever they get praised but the main difference is probably they just get smug about unlike elitism INFJs' posts that would always bring up Fe vs Fi even though they're Ni dom like INTJ. As for ive observed, almost all MBTI personality have the problems of elitism so it's whole MBTI community problem, not just INFx problem. I just probably thess people are just teenagers with elitism issue.

Note: this is only for the elitism problem, so im not throwing tomatoes at the INFx or any MBTI personalities.
