Banning religions in general is no effective move if you have a different goal than radicalising people. Christianity grew in the Roman empire at a time where being a Christian was punishable by death.
I don't see any Arians around.
Beware survivorship bias. If some religion was suppressed effectively, it's less likely that you'd have heard of it and even if you have, less likely that it would come to mind.
At any rate, my point wasn't just about effectiveness. It was that we have ideas about rights and we don't decide to suppress something just because it is effective, if doing the suppression violates someone's rights.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
