Did I ever tell you the story...?

here's the deal: I'm a young Marxist, and I own a Che Guevara shirt. Che is one of my heroes, and I do know what some people think of him. I am going to a camp that has international staff memebers, and I'm unsure of what countries will be represented. I may take my Che shirt, but I'd like to hear your input on what nationalities have the highest potential to be offended. I do not want to offend anyone, or unknowingly thrust my opinions on anyone. please serious, respectful answers only.
