I don't see an objective bit of difference between the strength of the beliefs of a Christian, Jew, Muslim, Hindu, etc. (& some of Coyoteman's favorites).
You believe the Bible is the inerrant word of God.
A Muslim believes the Koran is the inerrant word of God.
A Navajo believes his religion is inerrant.
A Hindu believes his scriptures are inerrant.
(fill in the blank on FSM).
In each case an adherant believes he is right and everyone else is wrong.
Since there is no objective proof for any of the world's great religions, there is no objective reason why only one or any one is correct.
In any case, at least 2/3 of the world is going to Hell by your reasoning. You are free to believe what you will, but you do not have the right to force other people to your beliefs, especially since the odds are that you are wrong. America is not a Theocracy.
Saying that the Koran is not the word of God is objectively baseless, just as Mohammed Ali of whereever would be wrong saying the Bible is not the word of God. The subjectivity of your opinion, as you so correctly pointed out with Mao's little red book, does not make your belief, the word of God.
I have made no such reasoning. That is your problem.
I'll call you a liar on the FSM.
