why do you think people have big egos?
just because they hold a view different from yours doesn't mean they are egotistic, or proud.
what the question you should be asking regarding others is "Do they put in any practice, and (at least) try to walk their talk; or do they make excuses to not have to practice and live up to their own words?"
but far more importantly "why should anyone comply to what you think?"
like one of my favourite Stephen Fry quotes says
Stephen Fry wrote:"It's now very common to hear people say 'I'm rather offended by that.' As if it gives them certain rights; its actually nothing more... it's simply a whine. its no more than a whine. 'I find it offensive,' it has no meaning, it has no purpose, it has no reason to be respected as a phrase. 'I am offended by that,' well so £*"&ing what!
I have seen many people who talk a good walk but don't try (or twist words to give a false appearance), and feign courtesy, respect, niceness just to feel superior.
