Nowhere is this worse than on college campuses.

At the University of Houston, a popular mural covers an entire wall of the Student Center. This travesty of art depicts the United States in the guise of a monstrous Uncle Sam terrorizing the strong but defenseless Mexican people, his foot stomping on a book labeled the "U.S. Constitution." When the school proposed painting over the mural during a renovation, such was the outcry from Latino students that the idea was quickly abandoned.
