I don't think that at all about INFP's. I know that inside they can be a real boiling cauldron of pretty violent hate, anger, resentment etc - they just turn it all inside. I know they can also be pretty ruthless as well. Far more in fact, than I'm capable of.
I reckon the biggest and most common misunderstanding I hear about ENTP's is that we're attention seekers.
True, we get a lot of attention, largely because of the way we behave sometimes, but it's utterly false to say that the way we behave is done expressly in order to obtain that attention. It'd be more accurate to say it's done either oblivious to or in spite of that attention being a possible result.
