There is this theory, there is reality. In theory there is no coercion in religion. After all, any political power that force believes down the throat will face fierce opposition.
In practice, without coercion, religions have lost their main use, namely a way to get others to do what you want. What can religions do nowadays? Offer better peace of mind? Much fewer would buy, like in Denmark.
So, we got this game where so many “pressure” is done on those who don’t obey and then people hypocritically say there is no compulsion.
There are. There always are. Tons.
