People still murdered and committed adultery and broke the Sabbath even after they'd been told that an omniscient being would definitely know and punish them. I think that was the poster's point, anyway.
But surely that's a strawman. No one thinks religion would stop all evil or all people, but there certainly seems to be some kind of psychological effect from being brought up in such a framework, which can be observed, for instance, in latent guilt and residual fear of hell and judgement that happens when people leave certain christian sects for instance, which is totally absent and baffling to those not from such a cultural background.
I think its eminently feasible that SOME people are being 'held in line' through explicit or implicit fear of rules/authority/sanctity/hell/punishment/purity/etc provided by religious and social structures.
Even if you use DDG, you go to a site with GA on it, google cdn, maybe facebook too, anything with those icons to share with a social media site.
Even searching for symptoms. I was searching for something my girlfriend mentioned the other day and now wondering if I'll start seeing some kind of ad related to the issue.
It's not good.
I eventually became a moral nihilist in theory, but someone that recognizes the importance of values in practice. (like a classical liberal against gambling.) And to tell you the truth, I don't know the proper, working way to instill values and work ethics (especially the latter) in people or kids. I, for once, suspect that I came to appreciate a respectful manner through seeing others shoot themselves in the foot by maintaining a rebellious attitude and feeling disgusted with poor manners at times.
Right-wing Millenials who aspire to be good parents often came to appreciate family values/religious values through the same way I did. by rejecting "degeneracy".
Note: I am not saying that right-wingers are morally superior.
