It’s a simple and powerful way to show your atheist pride.
This Friday, all you have to do is change your Facebook profile picture to the following:

And change your status to something like “I am an atheist” (or whatever).
That’s it!
For most of us, it’s a chance to show some atheist pride. For others, maybe it’s a way to come out to your friends.
It’s certainly not about antagonism. Here’s what Neil Moakley — an organizer of the event — writes about the event in an email:
… we hold the hope that some of the Facebook users out there with ill-informed impressions of the atheist community will see their friends list colored scarlet for one day, and maybe begin to realize that atheists are more diverse than our stereotype, and that we are often in fact productive, caring, ethical people that believers already interact with every day.
More information is on the Facebook Event page. Already, there are over 3,000 people signed up to “attend”!
(Thanks to Danny Piccirillo and Neil for starting and spreading this idea!)
