So yes, I believe atheists need not be arrogant, and those I know of in my own “real” (as distinguished from cyber) “community” assume nothing much differently than I do about the religious, or at least don't show it with arrogance. But then it seems that a lot of people who are irreligious want the whole world to know that they are too smart by half.
I think it is wrong to look at atheists on a board like this and then conclude that because many, most or all atheists here "argue" their beliefs here so arrogantly or adamantly that atheists are arrogant. The formats of a board like this promote discussion and that leads to some people feeling that others are trying to push their beliefs on others, when that may or may not be the case. I may think one of the atheists on this board is arrogant by the way he posts, and he may feel the same about me, but if I were to sit down face to face with him and converse about anything even religion or faith, we might see each other in completely different lights, in fact we might even become friends.
