AceNZ, I'm looking through your posts in this thread and you seem to be coming from a context, real or perceived, different than the one I operate in. You're taking what I see as a really polar approach accepting Rand's dichotomies of Reason/Mysticism and Egoism/Altruism not as a spectrum of positions but a spectrum of the population's psychology; that in your life people can largely say to be on one pole or the other. Is that the case?
My own experience has been that even the most religious of persons will fall in some middle zone and, in their major life decisions like marriage, death etc, are still dealing with the same basic problems, in the same basic ways as the rest of us. Very, very few Christians smile in a funeral.
Because of my own experience this talk of disowning others for irrationality boggles my mind.
Where is it you're coming from?
