We have atheists right here at F.R., they'd probably disagree with you (no, I'm not an atheist) God is and will be their Judge and He has said that He has a place for them, whether they believe in that place or not is immaterial.
It’s one thing to privately doubt or deny the existence of God (and no, I don’t promote mandatory church attendance or anything of the sort). It’s quite another for atheists to attempt to push out classroom prayer and learning about Him and His Word, while simultaneously promoting the “we-came-from-primordial-soup-so-the-only-thing-keeping-us-from-murdering-each-other-is-Big-Government” worldview. This atheistic worldview is precisely why test scores are plummeting, the entitlement mentality is rampant, and school shootings are increasing.
Learning about natural rights is an integral part of developing good conservative values; without God, the “natural rights” perspective integral to the founding of America would not exist.
