That's what most praise is, to you. Therefore you are more likely to view it through the lens of how you feel when you receive it. I think you are overlooking the function it performs for Fe users as recipients and are attributing disengenuous motives that are not necessarily present.
Because we all have to interact with each other, and because it appears that the needs of both camps are very different, I can't see what harm there is in any interested parties becoming aware of what will most effectively grease their respective wheels of interaction.
Statements like yours puzzle me because they seem unprovoked. You could make the same statement in a matter of fact, positive way and deliver the necessary information without causing offense. If there is no other motive than just self-expression of what you feel, it's hard not to just shrug my shoulder's and attribute it to immaturity or carelessness because it's the internet, but perhaps I'm missing something.
If a Fe user gets that blunt with people, it is usually because the messages they are responding with (which they believe are clear) seem to be going unnoticed. Therefore, your statement seems oddly hostile, considering the circumstances. No one in this thread has complimented you or even interacted with you and no one here is the other Fe users you have met in real life.
I'm only bringing this up because I'm curious how Fi users would perceive it, and if it isn't seen as harsh, what would be in their world?
