WTF?

What's wrong with wearing an American flag on one's t-shirt on Cinco de Mayo?
Well... If you happen to be a student at Morgan Hill High School in California - you could get kicked out of school.
According to the 2000 census, Morgan Hill was 27.5% Latino/Hispanic.
More recent 2007 stats show an increase to 31.3%.
Has being politically correct infringed upon the rights of students to show loyalty to the country in which they reside?

Apparently Roger Ebert forgets that this is still America and not (yet) Mexico.
No Roger, it would be similar to kids wearing an American flag t-shirt on Columbus Day, St. Patrick's Day or Juneteenth.
But then again - no one would see these as being racist or anti-(fill in ethnic group here).
