It is not just the fact that radical Uighars are being used as shock troops in Syria and elsewhere but the incidences/killings within Xinjiang. Then ... and only then .. it would be fair for him to lean to criticism of their radicalization prog. Like I said, not a fair shake from *that* presenter.
The other thing to remember is that China is not causing mayhem in other moslem countries like we do, so it is unclear what beef do radicals have with the government/Han ethnicity etc. I think this is being overlooked and needs parsing.
