Fe types often get a rise in saying things we don't believe in which often trolls Fi valuers lol. Words are more malleable for us, we take them less seriously by default I think. So a Fe valuer often pretends to be somebody they are not/opposite of what they are because it adds to the discussion & group atmosphere. And that's why Fe can more easily be "manipulative" and "two-faced" etc and also why it can be "nicer."
