I speak as a Muslim.
Belief must turn into sure belief. It reaches the point where when you are face to face with a lion, you are not fearing anyone but God, out of belief that God exists and does everything that happens. So there are no such things as "consequences for your belief".
Al Qaeda and so on blow up everything, even mosques, and that happens a lot. It's not just the West that is targeted. So don't say that Islam seeks to impose itself over other religions, or that this is Islam.
Muhammad (peace be upon him and his family) could not read or write. Since you agree to that it means you accept early sources. But what does it matter ? He never claimed he wrote the Qur'an. the Qur'an says : "We sent it down (the Qur'an) in a blessed night". It is the word of God sent down to the heart of Muhammad (peace be upon him and his family). Then he recited it to the people.
War is about conquering territories. So yes, Muhammad conquered and subdued people. He was at war. God ordered those wars so it's normal He spoke a lot of hate to those He ordered fought. As to rapes, I don't know what you mean by that.
The Qur'an and the Gospel comes from the same one and only God. It's most normal that they contain similar stories, specially knowing that prophets are sent as teachers. Their life stories serve the purpose to teach mankind. So one may find the same story in every revealed book. Just like Jesus keeping with him someone, though he knew (since he was a prophet) that he was going to betray him. He kept him close to him, he was teaching. (In any case Jesus was not crucified).
I speak as a Muslim. Whenever I read a passage of the Bible, it's obvious to me that it is a man made book containing intentional lies and forgeries.
Muhammad was at war, and war is war. Don't call him a terrorist. He did not decide by himself to go to war. God ordered him to go to war, and God authorized him to go to war against those who sought to harm the Muslims. In the beginning, he had to endure these things without fighting back. What do Americans do ? They bomb buildings, kill civilians and then try to hide it. You'll tell me it's a mistake. That's fine but they keep bombing though by now they know civilians will get caught.
The books were not written by prophets or their helpers. It was God who revealed to prophets the Torah, the Psalms, the Gospel, the Qur'an and so on. Then men changed those books, and put whatever they wanted in it and adopted these men-made books; except for the Qur'an which has been miraculously protected and kept authentic up to this day.
Islam and the Muslims are not the same. It's greatly unfair to yourselves to judge Islam by the Muslims.
