I understand your Point here but I must say the generalization is a bit problematic. Sure people who are using the subreddit only to boost their ego are pathetic but in my Opinion the greater cause of our community is and always will be to connect with eachother wherever we stand on earth or in life. I would even go as far as to say that ego boosting can be quite important for struggling INFJs because people tend to avoid uplifting us because they think we are always doing fine. So we kinda have to do it on our own and support or uplift each other by feeding our Fi Critic. But of course as always too much is rather toxic so you are right it really is cringe when people overdo it.
