I don’t think they are torching their own homes, since this is a xenophobic rampage. Majority of the citizens of that city are Han Chinese, something like 75% or more, I don’t know the exact figure. The angry muslims are targeting innocent Han Chinese civilians. This reminds me of the anti-Chinese riots in Indonesia by muslim mobs looking for a scapegoat for their poor economical lives, so they targeted the richer harder-working chinese. Once muslims see the real reason for their plight, their own religion, they might actually get somewhere.
This is quite different. The Indonesian Malays did not have their land confiscated from under them and handed over to the Chinese, as happened to the Uighurs. Xinjiang (China's name for East Turkistan) is 20% of China's territory, and all of this land has been stolen from Uighurs and put in Chinese hands.
Look at the evidence: Ever see three fires start simultaneously atop (at least) three high-rises?
Some (cell phone?) coordinated force (Uighur terorist group?) -- or some force with aerial access (government aircraft) is acting under the cover of the mob action.
There is something beyond PO'd (Muzzy) crowds at work there...
