So, this is something upon which I was reflecting

Religion is a bit different because it's so intangible. You could only realistically ban organised religious meetings or public practices. Further to that, you can't stop people believing any particular superstitious business, discussing it or practicing it in private.

The one thing you could try to also stop is indoctrination, although that would be extremely hard to police.

Personally I don't think banning any of it is a good practical solution. I think it's best to directly address any harm that results from it, and to educate people, including the psychological dangers of indoctrination. Ultimately I feel it will take a societal attitude shift, and it's one that is already well underway in much of Europe.

The other problem with trying to "ban" any sort of religious activity completely is that it's going to make things more divisive than they already are, and will probably make the extremists/fundamentalists (who are the real problem) dig their heels in further and be even more willing to take reckless action.

I think there's a good chance religion will be reduced to irrelevancy just by the natural course of education and promoting equality, in most civilised countries, within a few hundred years. I foresee it being the equivalent of old wives' tales that no one cares much about, although it still goes on. Islam seems to me to be the most worrisome barrier to this, with things how they are now. It seems, on the whole, to be less flexible to being watered down and integrated. I hope I'm wrong about that.
