I don't understand why some people in US so desperately want to claim the first place in human right violations. Do you believe "Chemical castration for certain child molesters" is comparable to mass injections of huge number of people whose only guilt is having whatsapp on the phone, or not speaking Chinese, or having a beard, or not drinking alcohol? Is low quality food comparable with getting small piece of rice dough the whole day? The way US treated prisoners in Guantanamo is probably comparable to the situation in china, but normal prison are not.
I think it is important to keep the sense of proportion, things can be bad and require urgent action without being the worst. And saying things like: Trump is Hitler or human right violations in US are comparable to China do not help anyone. It just downplays the seriousness of the worst case and make the bad case look good.
