So first, I'm dying to know how you also have "the protectors" after INFJ. I've got nuthin.
It has to do with the time that you joined, I think. At one point they stopped attaching the "badges" to the personality types (there might have been some anti-stereotyping protest against it). If you joined past October 2015, then you don't have the tagline there. That's my best guess, anyhow.
Now, to the OP:
I have personally come to accept that the majority of people I know will never get the "unfiltered me". A con of being an Ni-dominant is that it is very difficult to express what is going on inside (just think about it: Ni is the toughest function to describe), and being an Fe-auxiliary only makes this worse.
How? Fe is oriented towards what works for
everyone. If you're the odd one out, Fe will identify this and make you more prone to censoring yourself. Being one of the rarest types automatically makes you the "odd one out", and Fe's response to this is to try its darndest to make sure that you blend in to your environment (this often means pandering to xxSJ sensibilities, which are the opposite of our own).
This is certainly frustrating at times, but I've come to accept it more as a beneficial survival mechanism. Most of the people I interact with on a daily basis simply do not
need the unfiltered version of me. It isn't beneficial to them, and they naturally won't appreciate it very much. This doesn't mean that something is wrong with them or myself; it's just a matter of natural preferences and priorities. I don't want to hear the ESFJs talk about what they made for dinner last night, and the ESFJs don't want to hear me talk about my most recent contemplation on nihilism or whatever.
Don't get me wrong: I completely understand the feeling of loneliness that comes when you've had to deal with this sort of thing for a long while. I was in a pretty deep depression not so long ago because I was afraid that I wouldn't ever find someone who I could be transparent with. But eventually, I
did find those kinds of people. I met an ENFP who enthusiastically probed my mind and ate up every unfiltered thing I had to say about myself, and he became my best friend (and by the end of this year, he'll be my husband if all goes according to plan). I told him things within the first few hours of meeting him that I hadn't told my own parents. It was sort of magical.
Then another INFJ came along who could understand pretty much all of my personal struggles to the letter, and an ENTJ who occasionally loves discussing the deepest parts of our shared Ni.
Point being: don't lose hope. I almost did, but the right people came along just in the nick of time.
