Fe simply has the connotation of evil, or more specifically, conspiring to me subjectively. It seems to misdirect information in order to please some sort of social hierarchy based not on logical correctness but out of appeals (to people, ideas, society, etc.). I agree that Fe can be heartfelt, and in its truest, purest form, would be considered a force of benevolence, but with it muddled as it is in today's society, it is used to keep people within the constraints of social structure not based on some sort of empirical correctness but simply to preserve the harmony of society and/or the group.
The purpose of Te in terms of socialization is to quickly and efficiently apply knowledge, to show the realistic application of knowledge ("what's the point if we know how the aerodynamics of a plane work if we don't have a plane or aren't building a plane? Let's apply this knowledge somehow"). Essentially, Te is logical directness based not on subjective opinion like what I am utilizing here, but on justifiable, objective evidence.
Te people regard their success and mental prowess based on their external results, just as Fe people regard their success and emotional prowess based on their external results (in this case, pertaining to the emotional atmosphere)
