I agree that 'intolerance', as bad as it is, can be thought of as a combination of several others.

My nomination... 'lack of perspective'

not sure I can express it in one word like the others, but it includes the concepts of 'narrowmindedness' 'shallowness' 'isolationism' 'ignorance' and a few other words that express a deep reluctance to see beyond one's own inculcated habits and beliefs.

(note...'ignorance', in my view implies cultivated lack of perspective, rather than 'stupidity', which is genetic and/or incurable)
