I have done some research into the writings on his weapons and the patches he wore.

[link to en.wikipedia.org (secure)]

He wore a Black Sun Patch, the Black Sun has connections to The Satanic church as well as the SS Nazis.

His guns were covered in the names of Famous Battles against Islam (Victories over Muslims) such as Tours.

732 also appears to be written on his weapons a number of places.

so basically you have a guy shooting up mosques that has been brainwashed by the CIA to be a satanic nazi muslim killing machine by first person shooter games...
