I believe zer0 is a Marxist atheist but a cultural Muslim.
I know radical progressive types (Marxists or whatever they actually are). Their hatred of Israel and backing of Islam is always a given. Most of these people are atheist humanists. So it is a not belief system for Allah. It is an anti jewish anti capitalist thing that moves them.
I don't think a "cultural muslim" (whatever that is) would support radical muslims (like the Bro-hood and Hamas) in their goals.
If you remember, even Jeremiah Wright worked with Obama to make sure his muslim sensitivities weren't insulted by his Christian-fronted muslim church.
That's because Obama, like convert John Brennan, is a REAL muslim and a true believer in Jihad.
