Talking of freedom of speech, Islam gives the greatest freedom. Contrary to Christianity, Islam says a child is born free of any sin. No one is guilty of the sin of anybody else including the sins of Adam and Eve.
So no one is guilty of the sin of Adam and Eve. Why should anyone be? It would be totally unfair for me to be the guilty of someone else's sin.
This freedom from the sin of Adam and Eve also makes moot the theory of Jesus coming down to clean everyone from the sins of Adam and Eve. This theory had a catch: one had to believe in Jesus as a son of God to get this "coupon" of freedom from the sins of Adam and Eve. Wait a minute. What about those people who died before Jesus' arrival? They never had a chance.
