I'm a 4W5 and have been described as everythign from 'volatile' to 'passive aggressive'. In my experience, people see what they want in an INFJ, not what is there. Male INFJs often compensate with upfront honesty, but this doesn't work, other people's need to project is too strong.
As for what is internal to me, I was highly susceptible to what you describe. At first, this stopped because I couldn't play the role any more and live. But later, I started to see just how eroded and ancient the human condition is, and realize that there is no mesiah possible inside the primate body. At this point, I direct people towards the forces that I think can help them, and those are external to all of us. I would say that I am still reactionary, but perhaps not in ways that come across clearly to others. I'm not sure how to proceed with these thoughts,I would need your input.
