1st generation atheists tend to retain the moral order of the Bible (even while quibbling about their favorite vices); it’s the 2nd generation that questions why retain something if you disbelieve the foundation for it? That leads not only to rejection of morality but of beliefs in reason and science grounded in a rational lawgiver. We see this playing out all around us, and the 1st generation atheists are almost as alarmed about it as are theists.
The final state is a return to religion only it is a premodern pagan religion. That’s what’s coming out of the universities these days.
I have friends who would be best described as agnostic vs atheist and I always tell them that it’s in your best interest that your rights came from a higher order or God because if your belief is man can grant you those rights, man can take them away and that’s what we’re seeing today.
