I get your point but also want to point out that dictators ban religions because it usually tells people there is something more powerful than the dictator.
Did you know the same regions of the brain light up for self when people think of God? Maybe the dictator doesn't want anyone to think THEY'RE more important than the dictator, like in our society, where every individual is sovereign with rights, every individual is like a king.
does it work that way for non-monotheisticly based ideas of religion/God like the paganism or Buddhist varieties?
Not sure. I think it wouldn't, because it needs all domains. Like, I know myself can delve into any arena of life, whereas those gods are typically refered to as one domain. Perhaps something to do with a functional hierarchy, you'd think of yourself.
