Islam's Claim: God spoke to Muhammad

Evidence Offered:
1. "Look how beautiful the poetry of the Koran is." (appeal to art)
2. "Islam has grown and so it must be true." (appeal to popularity)
3. "There's scientific knowledge in the Koran that Muhammad couldn't have known."

I have to add at least one more point to your list. It is a very very common muslim claim.
For example a prominent muslim scholar who claims that in the foreword of his commented Quran-translation would be Muhammad Asad.

4. "If you read the Quran and do not get his divinity or the beautyful poetry, or if you try to criticice it it is because you did not read it in the original arabic and because you do not feel like an arab.
What ? You have learned arabic to perfection, lived for many years in arabic towns, studied the Quran in the original arabic and you still do not get his divinity or the beautyful poetry, or try to criticice it ?
You see : that is because you did not spend also years and years among the arabic desert tribes, for only they are really fit to understand the Quran.
I have to disqualify you as a discutant on the Quran and I have to disqualify your critic. you are not fit to criticice the Quran, for if you did not do all of the above you cannot have really understood the Quran.
(That is if you are a critic - If you become a devote muslim you did understand it after all.)

This way muslims can disqualify 98 percent of all Quran-critics
