And you have evidence that a Han Chinese man would not receive the same sentence for the same crime?
I am absolutely sure he would, but either way that is again completely besides the point.
It's about how China's political regime treats its citizens regardless of ethnicity. If it doesn't discriminate (which I think it does) and gives everyone the same unfair treatment that doesn't somehow make it better compared to the scenario where it did discriminate. It's the same.
Even if they were not coerced into consenting (which they were) that would be completely beside the point. They are arbitrary sentenced to death, they necks are tied to they can't speak at their "hearing" and their organs are extracted while they are still alive.
