In my experience, It's both non-factual (ego-less people are the first to learn from others when poised with new ideas) and short-sighted.
Now that you mention it, there are parallels with the "tolerance" ideologues. There are people who are naturally patient and empathetic, and then there are people who opportunistically pursue the in-vogue virtue of "tolerance", and end up practicing de facto intolerance in the process. Don't conflate the two.
Sleep tight. :)
You are correct, we can't "get them out"; only they can do that by exercising their free will to choose to become better human beings. We can, however, attempt to teach them with our positive ideals, attitudes, and behaviors, but we can only lead the horses' asses to water, not make them drink.
Note that we must remain humble and grateful in remembrance that we ALL used to be horses' asses, once upon a time, before we entered the Path of Love.
Ironically, it's the "egoless" crowd which tends to be ego-obsessed and solipsistic. They imagine an egoless world which simply requires that everyone thinks just like me; in effect, everyone shares the same "ego"/perspective. Only in this bizarre fantasy world can we move past the ego and focus on "objective reality". Ayn Rand is an example of this worldview.
