And that would be an lie. Once you revert back to sensible, you don't return to nonsense.You're conflating atheism and being sensible. Atheism is simply the lack of belief in gods. It has nothing to do with being sensible or not, as there can be non-sensible atheists.
This is true. I think the US is becoming more secular as people drift away from religion, but it does not mean that everyone is becoming more rational or sensible. In Europe and Japan lots of people are atheists, but it does not stop their governments from having stupid military, political and economic policies. People are becoming atheists in the sense that they don't believe in any of the standard ancient gods. But they are still prone to every other silly made-up crap idea that comes down the pike. They don't apply the same rationality in every area of life.
Like anti-vaccination, alien abductions, more guns!=liberty and freedom, positive thinking makes you rich, becoming vegan makes you a better person, you won't get pregnant/AIDS/herpes if the person is "nice", zombie apocalypse, melanin gives you magic powers, dreadlocks give you magic powers, communism or capitalism will save us all, USA!USA! but voting doesn't matter, if you get thin enough and pretty enough you will be happy forever, climate change denial, gay is better than straight, more piercing and tattoos make you look original and artsy, getting high makes you see reality better, white supremacy, and whatever Rush Limbaugh, Donald Trump, Jimmy Kimmel, Oprah or Ellen said today.Show me some good evidence
if you want me to believe something or agree with a policy; that has to be everyone's framework, for everything, religious or otherwise. It is a hard way to be, which is why most of us fall off the wagon from time to time.
Back in my Trekkie days, I hung out with lots of people who were, by every definition, atheists. They were really nerdy, smart outcasts with strange analytical personalities who had seen right through organized religion. But they had a fatal weakness- they were all one shaky step away from falling down and worshipping Mr. Spock, Dr. Who or Isaac Asimov.
We still need to emphasize rational thinking and the scientific method, even with atheists. Or we will all end up, disbelieving in gods but still trapped in a 1970's era sci-fi convention. Forever.
