Please define what metric(s) you're using to make that statement. I'm not saying you're wrong, but a statement of objectivity requires something to substantiate it. Certainly, the US doesn't have nearly as many political dissidents incarcerated, but China doesn't have a systematic problem with summary executions of a racial group by police (for example; there are plenty more on both sides, which are not necessarily comparable; yes I know in this case that China has its own minority racial group issues). Then, are scale effects (population size) factored in your figures?
