Prof. Yang has managed to write an entire diatribe without addressing the basic issue: Is it moral for anyone, including China, to sell arms to someone who is actively murdering it's own citizens? Apparently his answer is "yes" and his justification is"everybody else does it. so you can't say anything critical about me". I'm afraid that many people across the world, even those whose governments are guilty of equally shameful behaviour, would not agree. Some of those who point out the immorality of the act are reporters. That fact and the national identity of the person in question has no bearing on the inherent rightness or wrongness of the sale. This is a basic Fallacy of Rhetoric which the Prof. should be aware of: arguing against the man rather than the argument. Even journalists in China have criticized the Govt. for it's policies in Tibet and Africa, only to lose their jobs. Here's a point blank question for the Professor, and it only requires a simple yes or no answer: Is it moral to sell weapons to people who will use them to commit murder? Yes or No, no elaboration is required.
