yes the rude thing is sort of a collateral issue about how "rudeness" is in the eye of the beholder. EIE is not inherently rude since offense and discomfort and politeness are psychologically relative phenomenon. the best we can say about objective rudeness would be norms of Fe "be quiet at a funeral" type stuff; obviously chae does not come across as rude in any way in that sense. in fact she would probably be more well behaved than half the people myself included that chimed in about finding Fe or Se rude. so the rude thing should not be thought of as an attack on her but rather just an interesting example of how even a very decent human can rub others the wrong way and no one is necessarily at fault. such phenomenon are at the heart of personality theory and exposing them seems to me its most valuable aspect
