I have a respect for people who DO believe in God. A respect that keeps me from jumping in, and saying things to them like "You are wasting your time! Wake up and smell the coffee!"
I would never preach my lack of belief to anyone. So why is it I wonder that they feel the need to correct us, or say that we are blasphemous? Hasn't it been made clear that some of us are atheist?
The arrogance of christianity never fails to show it's face. Obviously, since we do not believe that God exists, then blasphemy doesn't really mean a whole lot does it?
And please don't say "well please show me respect by not blaspheming in front of me." How much respect do you show the Buddist, or the Hindu? Would you eat a steak in a restaurant, and there was a Hindu sitting at the table in beside you? Would you drink coffee if you were sitting at a table with a mormon that belives that you can't have caffine?
