Opportunity for someone looking to change the context of the debate:
Bring a large, but well folded Confederate Flag to, say, a Soccer game in San Diego. It is important that the game be between two American cities. When some La Raza type brings out the Mexican Flag, go right next to him with the Confederate flag.
All of those lefty liberal arts grads who spent four years comparing and contrasting will have their heads explode when they try to explain Mexican flag good, Confederate flag bad.
Not really. Confederates were God fearing gun loving rednecks. Mexican just want to take back what we stole from them in our imperialistic days.
