There is no double standards, you have a part of your country which has historically had a large muslim population, no where in Europe has a muslim majority area apart from some shitholes in the Balkans. Its a bit different than 1st/2nd generation immigrants who attack France, they know it isnt truly their home whilst with the Uighurs it is their home.
Look at this recentish bbc article
Three 'Xinjiang terrorists' shot dead by police in China - BBC News
Thats not reported any differently than the Paris attacks...terrorists killed in a raid, a description of the raid and how the police dealt with it. You are finding double standards which exist everywhere, you can also find normal reporting, it depends what your willing to look for, if all you want to find is double standard journalism then it isnt hard. I dont think you will find any "western" people who would side with the muslim population of China apart from some human rights PC pricks, the train station attack and a few others were heavily reported on here and had no double standards. Good job to the security forces in eradicating more scum at the end of the day no matter how you read the article.
