I wasn't speaking of atheism as inflexible in that second post, just some RF atheists.Perhaps they seem inflexible because of you're pigeon-holed definition that presumes that atheism entails an entire world view.
If you characterize atheism and frame it in your mind as inflexible, you will be assigning those values to them anytime you hear the label even if they are not really there.
You may not see a worldview in what you describe, but in a person who is open-minded, rational and logical, as well as systematic, I see a particular world being revealed to them, a world different from the person enveloped in, for instance, dogma and superstition, or mystery and magic.With that said, you are being pretty dishonest if you claim that it's "off topic" to point out that it literally only applies to one thing. No world view is based around atheism, rather atheism is a result of skepticism which bases itself around the value of verifiable and reproducible evidence.
I see a worldview.
People can cry about that all day, but life has been better since that attitude has permeated the sciences. For some, they take it further and discount even a deistic god (which itself is somewhat unnecessary from a philosophical standpoint and just pushes back many questions a step without really answering anything).
