what i'm trying to say is that both religion has its share of violence... this will never stopped, it will just transform into a new form of oppression and abuse because the root issue is not the one being addressed. Islam became a tool of their inspiration because they felt oppressed it's not the reason of their action.
Karl Marx once said religion is the opium of the masses and he is right.




that's why he said it's the opium of the masses
