Perhaps the people of the PRC value the stability that creates the conditions for their improving lives more than free speech and other individual rights. We, in the 'West', are in no moral position to say that their system is somehow wrong. Sure, we absolutely can and do judge; but we have lost the moral authority to say to the rest of the world that they ought to live by those judgments.
If the people of the PRC are not permitted to speak freely, then it is all the more important that the rest of us do. You are as entitled to criticize the government of the PRC as you are of any Western government. Therefore let us speak plainly to the matter at hand; let us not evade the issue by pretending we, as human beings, have neither the wit nor the right to look and judge; let us not be so naive as to think that an increasingly authoritarian and chauvinistic China does not affect the rest of the world.
