The sad news is that during a speech, Obama trivialized the situation by making a stupid remark about "Leave it to Uighur" as if that was funny.

There is nothing funny about this situation. On one hand you have a totalitarian and authoritarian government outlawing practices they don't approve of. On the other, you have people who are indoctrinated in their religion and feel justified in defending it violently. It's a lose-lose situation.
