The outcome of that may not be what you think it would be.
Most people with half a brain will become ex-Muslims after reading Quran. Problem with all religions is that not many people actually read the goat skin manuscripts of their respective religions.
Historically that's certainly been true, and Islam today coincidentally exists in many illiterate and poverty stricken areas.
But it's interesting that here we see both pro and anti - Islam persons suggesting, "read the Koran."
Really it's wise to go further than that, for example into a study of comparative religions. But it doesn't take much to reject the doctrines of Islam, unless perhaps one was in a Islamic society and culture and family, and must keep his opinions and attitudes secret.
