If a radical Muslim man hears that you said that Islam is evil, he'll kill you.
If a radical Christian man hears that you said that Christianity is evil, he'll kill you.
If a radical Jewish man hears that you said that Judaism is evil, he'll tell the radical Muslim and Christian men that you said their religions were evil.
A 'radical' Christian, whatever that means, should at least take his moral principles seriously. No Christian with fear of God would murder because some fool calls his religion evil. That'd be sinful.
