If you guys say ISFp, I say YES!
Otherwise I would have thought that I'm saying ISFp just because heath must be my conflictor. (the logic that everyone you don't understand or don't like are your conflictors).
I sense a hectic arrogant attitude in Heath's posts, "I only care about myself, I say what I want, I don't care what others think because I
make the social rules.". When Fe-polr (INTp, ISTp) people annoy others, they still care. INTps tend to be more careful about not saying the wrong thing (that's why they talk very little or try too hard to impress with book-information and originality.) And ISTps know that they will say the wrong thing but they do it anyway. The social rules are a strong pressure for them, so they try to fight against them by acting "like themselves". ISTps tend to defy social rules by principle.
Your attitude could very well be Fe, but I really doubt Fe-polr. ISTp could be a possibility (depending on the reason for your nasty posts), but VI says something else.
