Watched this the other night. Even though it's from hipster scum news outlet Vice, I found it pretty incredible. Maybe for Soccer fans this is normal-ish behavior, but I found it insane and fascinating.
I remember at my first job growing up I wore a Celtic jersey to work, and one of the chefs was apparently a Ranger fan. He gave me an incredible amount of shit, and was confused by my lack of comprehension of the rivalry and whatnot. I feel really bad after watching this.
The Lady (grew up overseas...Turkey) says this type of stuff is the horrible truth of football, but from an American perspective it just seems insane.
