For many people in post-Soviet countries, it was the other way around: raised as atheists, many of them found religion when it became allowed. I wonder if the same thing will happen with China.
Though the trait originates in the useless prejudices of the useless English, in a pluralistic, liberty-oriented culture it is a habit coincidentally serving several valuable purposes, none of which will require the clarification two decades hence that they would need just now. Unfortunately, liberty itself being entirely out of fashion among the nonces for the nonce to the fore, there is not much point either elaborating on or expecting the sorts of reforms which an aficionado of liberty, not at all the same as a soi-disant "libertarian," would appreciate.
