> The mad rush to as quickly abolish religious practices in mainstream U.S. culture without any form of societal replacement is puzzling to me.

In the US, it's been a slow process over 35 years, since 1991.[1] England and Wales are much further along - believers are below 50%. But Islam is on the way up in the UK, at 6%.

The high-intensity religions, the ones that require religious activity once a day or more, seem to be thriving.
