all others are excuses, as long as there's segregation, turmoil is not going to end. it's die or live independent.
in uighur's minds, hans being there is already original sin, how many carrots/candies they bring won't change that. and the economic differences between two races or other injustices to minorities is really exaggerated. all poor, under-educated people struggle in today's china, no matther what race.
you can denounce ccp for injustice to lower, poor class people, but don't say they do more to minorities, it's just not true. on the contrary to make sure minorities obey orders, they send many carrots/candies.
here're two very vivid portraits, 1 of a han, 1 uighur family. life isn't easy for either.
