we don't create problems so much as we see potential tensions in places before others do. sometimes this means we exacerbate tensions to the point of having to be addressed, which is what others call "creating problems". other times we're the ones gathering people together to stand up to injustice before injustice morphs into tyranny. defensiveness can be used for good or evil, just like every other trait described on the enneagram.
anyway, i'm glad you decided not to just rant, but "e6 is the worst enneagram type" isn't really the most educated title for a thread. honestly, you're lucky to have gotten some coherent and patient responses. in the vein of problems being created, it always takes 2 people to create a communication problem. if you are having trouble with 6s, there's probably something you're also doing to them to make them act the way they're acting. the rather easy thing about 6s is that we're a reactionary type: we don't initiate; we respond to you. figure out what it is that you're doing to make us uncomfortable, and the issue will immediately disappear.
