As an OLD atheist, I left the whole "I need to tell other people how stupid their beliefs are" behind many years ago. It became pretty obvious to me that there are plenty of atheists out there who believe in things just as silly, if not moreso.
Look at all our fellow atheists who practcally worship Marx like he was a prophet, or have little Che Guevara "iconography" all over their apartments. (It doesn't WORK, kids!)
So I wonder, knowing that people from "the other side" who harangue and get in our faces because of our lack of beliefs are really just annoying a**holes, will other people look back on these times in their lives, through the dark glass of maturity, see themselves behaving in the same way, and say "man, I was just as poorly-behaved as the people I despised?"
Or will they see themselves as worse, because, as the "more civilized, rational people," they ought to have known better?
I doubt it, but I just thought I'd check.
