Religions at their core aren't bad, they are created to be used as a manipulation tool to pervert anarchy and chaos by putting rules that supposedly some kinda of god created.
They become unstable when few sides beliefs collide therefore new age or modern age needs new rewritten religion by some none existent god.
Just like my country that uses Religion as an excuse to manipulation people to follow the dictatory of mr x and y because their leader chosen by god or make them follow some king or family because their blood is different or connected to prophet or something.
Is it hard for a muslim to leave his religion behind?
