Bill Gates, Warren Buffett Star in New Atheism Campaign.
Bus posters via the Illini Secular Student Alliance. From their website:
"Religious groups have...duped Americans into believing that Christians are the major givers and that non-believers are selfish, angry loners unconcerned with the struggles of the less fortunate." They go on to say that the message of the campaign is to remind us that "the largest scale humanitarian aid projects in human history are now conducted by atheists."
A secondary unstated message seems to be: forsake God, become rich as Hell. (these are the only executions in the campaign). The Pope is making his Grinch face at these two heathens. Here's a round-up of previous religious marketing.
