Stop, I can name almost a dozen off the top of my head, Brian.
The LRA in Congo (No Religious affiliation), Kahane Chai, in Israel (Jewish), Aum Shinrikyo in Japan (Crazy hodgepodge of Religious affiliations), IRA in Ireland (Formerly Catholic, now not so religious), UDA in Ireland (SUPER MEGA Protestant. Interestingly, very much in opposition to the IRA), Shining Path in Peru (Stated Aethieists), ETA in Spain/France (Catholic), FARC in Columbia (No Stated Religious affiliation, most member probably Catholic)...
You are too smart to be saying shit like that.
