Omar Makram is spot on. Watch and watch again.
0'27": "The best cure for religion is studying the scripture"..... Reading is what made me an atheist"
1'18": "Hadith more violent than the Koran"
2'25": The level of violence in the Koran is unacceptable to me"
2'45": "The Koran is incompatible with human rights"
3'25": "Mohammad as a historical figure is a fucking awful person"
5'20": "I might as well believe in werewolves or vampires, or Greek gods"
I found all these in my readings of the Koran and the Hadith. What I don't get is why people should convert to Islam, after reading the scripture. Either these people haven't read the scriptures, or they have and they find them congenial (hence explaining whey so may converts become "radicalised" jihadis).
Less common is the conversion from Islam to atheism, as Omar explains in the above video. Mainly, I suppose, because of the penalties for becoming an apostate: coventry or death. So that makes Omar not just an honest and thinking man, but also a very brave one.
As of writing, the comments are all supportive of Omar.
