That is an interesting thought. It might also help explain why we have become far more polarized as a nation over the last 20 years. I think net/net we are better off as a society though, I don't recall the source, but I do remember reading a research paper that concluded that colocating minds had a multiplicative effect on increasing scientific knowledge.
On a somewhat related note: A lot of people cite the "faces of atheism" meme/trend whatever you want to call it as being the tipping point when /r/atheism just went too far and it became cringey. I mean some of those posts were a bit cringey, but overall I think it sent a very needed message- that there are lots of people out there from all walks of life that think like you do, don't think you have to give in to the prevailing beliefs. I don't think my upbringing was that abnormal- questioning the existence of god, my parents/family would have smacked me, probably verbally but if I really pushed it they likely would have punished me. My friends all seemed to firmly believe as well but were generally tolerant, it certainly seems you could be a social pariah in more religious parts of the country. Being exposed to new ideas like this I am sure spawned some people to say to themselves I don't have to go along with all this crap, there are bigger and better things out there.
