It's because he was educated in a madrassa in Indonesia. This isn't exactly hard, folks.
Oh and stuff like, "I believe the muslim call to prayer is the most beautiful sound in the world?" Dude, wtf?
a) it's not a madrassa, it's was a private school - it's like the difference between a Catholic School and a Seminary... I went to a Catholic school for a time... I'm not Catholic. He was then sent to a public secular school... so PLEASE get a clue and stop reading RW bs.
b) Have you ever heard the call to prayer in person? I have, and despite my sheer disagreement with much of the religion... it is actually quite beautiful to hear.
