I know it may sound stupid, but are most regular internet users atheists?
Specifically, on YouTube, all the videos promoting religion have more dislikes than likes, while videos that oppose religion, i.e. Thunderf00t, Richard Dawkins, Christopher Hitchens, The Atheist Experience, etc. have a lot more likes than dislikes and also a lot more positive feedback.
In one particular example, educator Salman Khan, whose username on YouTube goes by khanacademy, usually creates videos teaching people topics from addition/subtraction to differential calculus. He also teaches evolution by demonstrating how natural selection works. His videos always get positive feedback and his videos rarely gets any dislikes.
But in one particular video, he hinted that our complex universe MAY have been created by an intelligent designer, and it's the only video which has a significant number of dislikes and hate comments.
This is not conclusive evidence in itself, but what do you think? Maybe there are more closet atheists than we think. Or maybe God doesn't want believers to go on the internet or they'll learn too much.
