One thing the Mexican Constitution has that we should consider doing.Mexico has no hyphenated Mexicans. They prohibit any reference to race when they conduct a census or issue any means of identification, Where a physical description is needed skin color yes but not by race or nationality or tribal background.By doing this Mexico has avoided “balkanizing”, creating fractional disputes in areas where a given group in one of its states is a majority or a minority.
Balkanizing would be good to let you know what neighborhoods to stay away from.
