It's really hard to figure out the mindset of the person/folks behind Ogrish.com. I check out their site maybe once a year to remind myself not to do foolhardy things. Don't play with explosives or incindieries, watch where that gun's pointed, don't play with a running lawnmower, don't drive cars and motorcycles as fast as they will go, and stay the hell away from just about any Muslim. The consequences for being stupid and careless can be very severe. The consequences of ignoring what your enemies are capable of can be very severe.
I learned everything I need to know about Islam by watching an Ogrish video of a man being pulled apart by two cars while a large crowd watched.
I really don't think that they have a pro-islam agenda in the slightest. Awhile ago they used to have a forum with each gruesome video they had. The islamic ones always brought calls for world war over it basically.
To me, they seem fairly neutral politically.
