I've memorised large portions of the Qur'an and Hadiths (Sunni School of Bukhari and Muslim) and Shia (Jafaari) to win Muslims over to Christ and I can honestly say based on friends who have converted and people I've debated with, the Islamic Dilemma is the nail in the coffin.
Now that the internet is filled with Apologists and countless debates which everyone should watch, you can understand why they're saying that Islam wasn't ready for the internet.
