Atheists are particularly keen on the idea of religions as meme complexes, and think of them as like viruses infecting other people’s brains. They regard themselves as immune. But materialism must itself be a virus-like meme complex that infects materialists’ brains. When the materialist memeplex is particularly virulent, it turns its victims into proselytising atheists so that it can jump from their brains to as many other people’s brains as possible.
