2 youtube channels debunk the Quran and the creed of Islam check them out; therationalizer and CEMBadmins. I'd also advise you to check out the channels theramintrees and evid3nc3 for well-presented, respectful and insightful critiques of religion. I'm an apostate from Islam BTW. Islam isn't rational, I defy anyone to watch those 4 channels thoroughly and then still believe that Islam is rational.
