I’m not entirely convinced that simply banning an entrenched social idea or practice is always (ever?) effective.
Of course I might be wrong. I’d be very interested in learning of just one example
Some things which have been banned and did not just go away:
Alcohol in the US; prohibition.
The church banned sex outside marriage,and still does.
The church has always also banned masturbation.
In our society at least, sex between adolescents has been banned for centuries. It seems to me that many parents still have a problem seeing their adolescent children as sexual beings
Both the Soviet Union and the PRC tried to ban religion. Looking at those places today, religion seems to be flourishing.
I’m unable to agree that religion has held back human progress, especially since that does not seem to be the case in China or India.
I think it may be reasonably argued that religion slowed down progress in Europe and the world, up to the enlightenment in the18th century.Then came the industrial revolution, and continuous development up to today. I’m not convinced we would be any further developed if there had been no religion.In my opinion, we can speculate but not prove either position.
MY basic position on religion has not change: Religion is literally universal and has been so at last since the beginning of recorded history. It is we atheists who are in the minority, not the believers , in all of their diversity.
It is my opinion that religion only exists, on the scale that it has because it meets important human needs. I think religions almost certainly have some [social] evolutionary benefit.
IMO it is no accident that as countries become more affluent, the need for religions decline,and countries become secular.
Today, significant religious growth may be correlated with lack of development, poverty and ignorance (uneducated) I can’t prove there is causal link, but I suspect that is the case.
Have a look at the US.It seems to me that as groups, the most egregiously dogmatic and superstitious believers are found in areas of poverty and lack of education. Have a look at the US bible belt. Seems to me these states are the poorest in the union.
If religion is banned or restricted, people will have those needs met some other ways, typically through personality cults; EG Nazi Germany, the soviet union, Maoist China and the Kim dynasty in North Korea.
