He’s not so much Muslim as he is anti-christian.
The Muslims get his sympathy because they are anti-christian as well.
As far as a Muslim is concerned, repudiation of the moon god bears a death penalty, regardless of what subsequent belief is adopted. Whether or not he is apostate is not a matter of what I think, but what they think. There is no fatwa.
For one who is not a Muslim he certainly spends a lot of time and energy praising Islam! I have yet to hear him say “Holy Bible” but he has said “Holy Quran” many times. If he mentions the Bible it is just the Bible but the Quran is ALWAYS, “The Holy Quran.” When do you ever hear a Christian or anyone other than a Muslim refer to the Holy Quran?
