Why are you afraid of a religion? It is only Isis you should be afraid of, I am muslim and follow Islam and there is nothing wrong with the teachings of Islam, Isis claim to be muslim but even other muslims don't agree with them. What if I just said I was afraid of Christianity? That is unreasonable. The religion alone is not dangerous. Extremities can be. There is no rule in Islam that allows you to just do what Isis does. Isis is a terrorist and extremity group, you should be afraid of them not Islam.
