Any racial conflict is complex. When you see those tragic, horrendous, gruesome sights in the media, your racial instinct kicks in first. You go with your own. It is understandable.
Well other non-chinese watch it with sympathy too, though to less extent. But they do wonder what trigger one group of people slaughter another in such a horrendous manner. There got to be reason. You can shout, stir up revenge and even kill. But the rest of the world do have reason to suspect that something wrong with ethnicity policy consigned by CCP, given what we all know about CCP and recent turmoils in Tibet and other part of China.
In such racial conflict, average citizens are the most vulnerable as this case show.
Personally, having seen how effective CCP handle turmoils among Chinese in recent years, I do not believe they would have better way of dealing with inter-racial ones. We'll see.
