Would you say the same thing about those from Muslim countries who have engaged in terrorist activities against the US? Many of them travelled half of the globe over to carry out the attack and many were willing to sacrifice their own lives.
that's always what Western talked about the terrorism attacks in China. If the same thing happened in China, it's not terrorist, but fighting for freedom, while, if it happened in any west countries, it called extremist terrorism. If you don't care innocent Chinese people, why they would care your opinion? Who give your right to ignore the death of hundreds civilian's to maintain a fake peaceful appearance.
If China was peacefully coexisting with them and allowing them to perform their religion freely, it makes no sense that they would feel the need to attack random civilians.
