But do you not see that calling someone something like an 'ignorant fucktard' is counterproductive to your goal of ridding the world of silly superstition? I would never advocate you have to censor yourself(except if you violate the rules here), but I think you are ignoring the issue of how important choice of words and tact are to convincing people to let go of their dogma. You are more than free to call them fucking idiots, just don't think it will ever do any good as it will mostly likely cause harm to your goals..
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
