N.B. its really only against Christians that freedom is not allowed
this may be because Jesus said, "I Am The Way, The Truth and The Life, no one can come to the Father except through Me" This exclusivity, like the Jews being chosen as "God's people" makes them intolerant of other religions and so they cannot be tolerated
it may also be because, as Paul said in Romans 1: 18-19, "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, because that which is known about God is evident within them; for God made it known to them"
the truth hurts more than fiction and as they know it is true they fight against it only
