Question for atheists - part 2 :o)?

You're overstating the significance of terminology that most atheists don't use. You are also forgetting that when they are used, particularly on a board like this, they are self perpetuating meaning that one person uses a word like "omenosis" then someone else is likely to pick it up. Anecdotal incidents like that aren't enough to draw conclusions about all atheists or even a large portion.
