Atheism is a religion.

[Jenny A]

Atheism in certain forms can be viewed as religion as can many other ideas per the definition "a pursuit or interest to which someone ascribes supreme importance."

I doubt that for many atheists, atheism is a "pursuit or interest" let alone one of "supreme interest"--rather fewer as a % than say chess enthusiasts or liberals or tea party conservatives. I'm enjoying the forum, but "supreme interest?" Hardly.
