People in general are pretty terrible at truly understanding the perspective of others. They are OK at putting themselves in others' shoes, but not so OK at putting themselves in others' experiences and personality in addition to the shoes. Atheists certainly don't have a monopoly on this weakness, nor are we immune to it.
I think most people are like this to various degrees, although barely anyone believes it of themselves. I do think that as a (very general) culture, atheists tend to promote the ideal of being open to new ideas, if not always the practice (many exceptions in both directions, obviously).I find it disturbing that people ever come to a point in their life where they think they've figured it all out and put a guard up to new ideas. But I'm willing to accept that even this will change for me as I encounter new theories and people.
Hmm, this is a bit of an odd thing to say. Many impulses are "human" but not particularly "good" - murder, greed, cruelty, self-interest, laziness, etc etc. I don't think that criticizing any particular human tendency implies that you can't support the positive traits of humanity.I'm still coming to grips with the fact that, on this subject, I'm in agreement with the dude who wrote "Men Are from Mars, Women Are from Venus," but this line always comes back to me: "It is a funny sort of humanism that condemns an impulse that is peculiarly human. Yet that is what evangelical atheists do when they demonise religion." The article it comes from is really good.
