I guess the old post WWII text books calling America a melting pot were all burned by the time you went to grade school. Lotsa folks don't wanna be melted today but they do insist upon equal rights.
It is good to be honest about your experience but my first reaction was one of disappointment with crude tribalism. Nowadays when there are more white kids on one soccer team they chant USA USA at the more Hispanic team. Kids chant all sorts of racist crap more frequently recently.
