I very much hope that this execution does not go ahead in China, although I fully expect that it will. But those shouting loudest against the Yellow Peril have no compunction about the execution of the mentally ill, among others, in America, and would cheerfully reintroduce the loathsome practice of capital punishment here, including for those who merely happen to be their political opponents.
They certainly would not see whatever "bipolar disorder" is (there was no such thing less than a decade ago, and it is so limiting that Stephen Fry has it) as a mitigating circumstance here. Nor would it be so regarded in the country to which they feel their patriotic allegiance even though it is in no sense their own. Never mind in certain others places to which they are almost as loyal, such as Saudi Arabia and Uzbekistan.
