What country is Chicago a part of?

I could understand this in Guadalajara but not in Chicago.

A recent Mexican Independence Day assembly at Larkin High may have taken cultural sensitivity one step too far, a Larkin parent said this week. Robert Bedard said his son was reprimanded when he declined to stand for the Mexican National Anthem during a ceremony at the west Elgin school last month. His 17-year-old son, a senior in the process of enlisting, feared honoring another nation’s anthem might jeopardize his military status. Sitting down cost him a trip to the office.

The article is ostensively about a student being disciplined for not standing during Mexico's national anthem. No, the real issue is why is a Chicago school celebrating Mexico's Independence Day? Schools waste so much time trying to teach cultural diversity that other subjects get shortchanged on time allocation. The school day doesn't get any longer when you spend X number of hours preparing for a Asian-Pacific Heritage Celebration, Black history month, or whatever else. Schools are scared of offending the various "groups" instead of being concerned about educating the only group there that matters, the students.
