Although McVeigh hung out with the "Indentity Christian" loons at "Elohim City," he's likely to have been a disciple of that what's-his-name Turner Diaries author out in California in respect to religion as well as Z.O.G. What's-his-name was an atheist who derided both mainstream Christians and the religious types in the racist/anti-semetic movement. McVeigh was at best a nominal Christian, and may not have even been that. There's certainly no evidence, or reason to believe, he was anything else.
A while back,two black American brothers were picked up for terrorist involvements in the Philippines.One of them had converted to Islam,it was reported.
IIRC,when being photographed by reporters,one of them kept saying "(we) are Christians".
I haven't heard what happened with them but when they were picked up,it crossed my mind that the second could easily have been Islamic,also.
The Islamics don't seem to have a problem with lies if the lies might help them in any way.
