I think it's the best way, really,when discussing the subject. I have had atheists accuse me of not being...(what? Godless?) enough because I don't try to de-god-ify everyone I meet. These are, of course, the same people who spend endless hours complaining about door-to-door religionists trying to force their beliefs on them. O! The irony! It brings back memories of Chabbad trying to re-kosher my kitchen.
I *do* pipe up if science or politics are being affected by religious intrusion- besides that, and actually trying to (or succeeding in) kill someone, whatever you believe is really up to you and no business of mine.
I am more concerned with actions than beliefs. It is through actions that we build or destroy ourselves.
