Not sure if you guys are aware, so I'll enlighten you...
The "Nation of Islam" in question here is a support group of people and helps them with guidance. Snoop's support of them does not in any way indicate he's a full-blooded muslim, even with him saying he shares views of Farrakan.
The Nation provides a community for people and celebs often dive in. Nothing wrong either way, but religion isn't a white-line thing.
Beleive me or not, I don't know Snoop well, but even with the few times I've been in his presence, he's always shown strong christian background. Take that for what it is, though. I was raised christian active in the church since a child, went through a point where I studied 5 percenter culture, islam, and other religions that I walked away with beleifs from, and at this point in my life, I'm oblivious to all and any religions while remaining forever god-fearing.
When people try to make sense out of other's beleifs, you'll always hit a dead end.
