... We do not wish to ridicule the Atheist's lack of belief in Almighty God and the Savior Jesus, and we accept and understand that despite some bitter rejection of the modern-day truth, Atheists in the USA, do, in fact, have their own recognised religion, their own church buildings, their own ordained ministers, and their own weekly Sunday assemblies.
According to a 2005 Wisconsin Federal Court ruling on the matter of Kaufman v. McCaughtry, atheism is a religion. Apparently, jail officials blocked a prisoner from creating an inmate group, to study and discuss atheism.
So it went to court and the incarcerated man, won his case.
Yes it's true, it's weird and it's easily misunderstood. There are 'religious' organisations who call themselves churches of atheists. Their main objective is to disprove the Bible and its teachings. Even more astonishing, is the Skeptics Bible! It's identical to a Christian Bible, except it has a 'skeptics' commentary.
