actually, lots of members of high society would be quite refreshed by your honesty (especially the INTJ frank, polite objective kind of honesty). the people you're talking about are more specifically those who made their wealth through social connections and appearence. their loathing is a combination of envy and fear. it's usually poorer subcultures that require a more silver tongue as they're more likely to react strongly. self made rich people are just the opposite. they value genuine people with whom they can have an honest conversation.
is this behavior exclusively sx first? I'll have to reconsider sx/sp if it is (although I think it's mostly Fi/Te)
PS: I think you're an 8 or a 1. I don't see much 5-ishness in you and there is absolutely nothing 6-ish about you
