Forgive me if most of what I've said appears off base, but I have a limited amount of patience and should be doing something more productive anyway. From what I can tell, the problem arises here because BlueWing has attempted to classify the 'NF temperament' in general according to both type theory and general observations. As most NFs, myself included, tend to self-identify with many of the descriptions, many of the generalisations BW makes, especially where they are seen as derogatory, has the potential to cause us great offense. In particular, as xNFP types have a strong Fi we would perhaps be the most ardent defenders of individual rights, and would class BW's attempts to categorize and classify people by way of an overruling logical principle as inherently flawed. I am reluctant to classify myself as exceptional, and I cannot say that I do not identify with many of the flaws pointed out in this thread (particularly 'finding a subjective purpose in life', which I believe will be ongoing for some time, and I also admit that I can be wrapped up in myself. I do try to overcome these tendencies though, and especially with the people I value most, I always try to give them an equal amount of appreciation and understanding, and I would class myself as very loyal. this is perhaps because, despite my self-absorption, I often have a genuine interest in other people in general. however, in an attempt to broaden my perspectives I believe I am more capable of objective analysis than you would expect - and if this is not the case, show me how it is not so. at the very least, I make an effort to see all possible ways of perceiving an event, both subjective and objective, which is more than can be said for BW)
I do not feel as though people have to justify the way they feel about things, as their feeling is inherently justified due to the events that they have perceived up to that point which lead to a particular feeling. However, where that feeling does not apply to objective reality, I can acknowledge that a feeling is the result of a misguided and incorrect perception, and attempt to clarify the situation for people in order to further their understanding. It is not, however, the feeling which is not justified, merely a feeling that has arisen due to an incomplete understanding.
To BlueWing - as you yourself have said that you would prefer a world in which there are no Feelers, and you believe objective and rational analysis to be the only meaningful way of communicating, then I have little motivation with which to expand upon my arguments should you not understand them. In fact, I am rather surprised that for someone capable of such detailed, in-depth and often helpful analysis you have not found it within yourself to surpass this level of intellectual narcissism, but as it clearly does not bother you then the consequences will be yours alone to deal with. All I can say is that I do not believe it is possible to be perfectly objective, nor do I believe a subjective perception is inherently inferior, which is why I attempt to understand things as completely as possible. If you will allow me an opportunity to be self-absorbed and generally dismissive, then I would say I would prefer a world in which everyone is able to see past the trappings of their own way of thinking and makes an attempt, whether or not it is successful, to see as many perspectives as possible in an attempt to clarify their own. However it is not my place to say such things nor will doing so make them a manifest reality.
