Fi is actually much softer and more mutable than I think it comes off. It can become extremely rigid when we sense injustice or pain, in the interest of protection, but once there is evidence of compassion from the other side, Fi relaxes to an incredible extent. I think it's actually fairly easy for Fi users to adjust internalized ideas / character, but we need to see it in a friendly light to be willing to expose ourselves like that. If we feel threatened or judged, we're going to lock down completely and those irrational ideas will remain untouchable from the outside.
You'll often notice FP discussions in forums tend to be "Well I ____________", followed by "Oh yes something similar happened to me yesterday _________", followed by "My take on this is ________________". It's very ego-centric, it seems, but the idea is that you know what you want to share, but I don't know what you want to share, so I'll share what I feel comfortable sharing, and then you can share what you're comfortable sharing. It's understood that anyone is welcome to contribute when they feel comfortable doing so. We don't try to push our understanding of things on others when we feel like we don't have a good grasp, including other functions. We'd prefer to talk about what we know, as we assume those who are well-acquainted with the other functions will share what they know and we can learn from them.
Where do you see these issues with Fi in particular? Maybe some examples? I've never really heard Fi and pride linked much before.Sometimes generates self righteous attitudes of "look how unselfish I am compared to you." Oftentimes associated with false pride. Its users are the most likely to make threads that say "Don't take MBTI so seriously, its just a tool" and "don't be so judgemental [like I am toward you]." Most likely to deflect others for its problems so it doesn't have to deal with them.
