By showing that Fe can indeed be abused by its owners, you raise questions about its sincerity in general.).
I did not make this charge.
Destructive criticism is property of Ti and not Ne. Unhealthy INTPs criticize not to undercut others, but simply to point out fault. Since they are so into their T they either misunderstand or disregard the interpersonal implications their actions carry. So you cant say they trash people.
Could there be Ne cant? Sure, but thats more a property of ENPs than INPs, as that would be merely sharing information or asking for perspectives of others just to lay them out to the table without doing deep brainstorming. Can you convict me of this? Certainly, as often I ask for perspectives of others without really taking them in consideration. Though the destructive criticism bit, I take it was much more of your concern than that. This you've misattributed to unhealthy Ne when it should have been attributed to Ti.
Now, a good question to ask is, why is it that INTPs who supposedly dont mean to undercut others with their criticism strike feelers as maliciously and unmistakably destructive. Because the Feeling function is negative (our inferior functions tend to be negative because we tend to have an attitude of discomfort towards as they come to us with great difficulty) and hence negative feelings are directed at the object of INTPs' criticisms.
But thats long in the past for me, I am well aware of the impact my comments carry on others. Personally, I enjoy criticizing very much and I dont think there is anything wrong with it as long as you are aware of the interpersonal ramifications of your actions. As well as take the proper means to prevent harm from ensuing as a result. I dont think that a fetish for criticizing is evidence of neurosis.
I am not trashing the whole type of INFJ, just their neurotic representatives. You could draw a parallel to similar ridicules of other types.
*Again, in this thread I am not asking for help with how to deal with INFJs in general, but only with the very unhealthy ones. They are the ones afflicted with the cant problem.
Again, it sounds like Ne cant coming from an immature INTP: Your Ti is very self-involved; your Ne makes the world seem very intrusive and puts you on the defensive; so you use Ne neurotically to dream up ways to attack and minimize the biggest bugaboo of the INTPs: Fe. ).
The reason why I cant deal with neurotic Fe is not so much that it is intrusive but more because it is simply destitute of true depth of feeling. I'd be kidding myself if I thought I could have a relationship with such a person, as then I'd have to befool myself into thinking when its manifest to me that they're putting on an act.
Keep in mind, neurotic Fe, as I use the term is by definition what you call 'abused by its owners'.
