It seems the big ‘insult’ from theists is to say, “But atheism is a religion, too.” And this gets atheists ruffled up and fighting amongst themselves over whether atheists “don’t believe in any gods” or “believe there are no gods.”
The semantics of the whole argument distract us from the tactic itself. The claim makes it sound like the theists are agreeing that religion is a bad thing. They may just be attempting to make a point that atheists are hypocritical. But whether some people define religion as a ‘belief system’ or whether it has to have some supernatural element, I think that when the ‘atheism is a religion’ argument is thrown into the mix, that’s the time to pull back and simply say,
“Well that’s not my definition of religion, but even if it were, so what? It has no bearing on whether or not a god exists.”
Myself…I’m thinking about becoming a High Priestess in the Church of the Everlasting Atheist and demanding all my tax exemptions.
