So now you're changing your story? You don't have to join any ring and believe in god. If they have a prayer, you sit silent, and be respectful. That's called manners. Uncle Sam? Who do you think you are? So they say something along the lines of they support their troops, or something stupid like that. Big effin deal. Who cares? Sit there, shut up, and ignore that part, or sit there and observe, learn what happens in America. That's why you're at this school right? Oh wait, you said you didn't want to participate, but you're down for exposure. You're truly an idiot. You can't fully be exposed to a culture without experiencing things they do. So eat the turkey, and be happy, be full. Don't worry if they believe in God, or if they support "Uncle Sam." You'd support your military if they were at war? Even if you didn't support the war? Or are you so shallow that if you had friends who went over, you'd turn your back on them because they're stuck there because it wasn't their decision to go fight. Fuck you dude. Open your eyes.
