I'd say that modern-day Atheism is a cult. It's no longer just a position that an individual holds. More and more atheists are coming together in groups, voicing their opinions in places/forums devoted to atheistic views, and even designating some atheists as a sort of spokesperson, if not someone to follow. Such persons have even set up tenets for atheism, the way religious leaders have in the past and currently do. I would not be surprised to see Atheism be fully organized in the near future like many of the big religions out there.
It's like when people used to just believe in god and there was no such thing as creeds, doctrines, etc.
