The High School in my area(Fort Hamilton- 5,100 students) has an Arab club, black club, Latino club, etc., but no white kids club unless you count the one for the Greek kids.
But seriously, my school in the Bronx had an Italian Club, a German Club, and a Gaellic Society. The reason they had "African American" Clubs is because of the unfortunate fact that most black teenagers have no way of knowing what their true nationality is. The reason they have Asian Clubs is because there are rarely enough Asian students of one single nationality.
