this headline was that Hong Kong's former Chief Executive - apart from confirming Godwin's Law - has lost his marbles. Reading the article only confirmed this. There are several layers of irony here - one being that the hysterical over-reaction of pro-Beijing forces in Hong Kong, and CY in particular, has done more to bring the ideas of Andy Chan and other independence advocates to public attention than they could ever have achieved unaided.
Another irony is that if you are seeking a genuine contemporary equivalent to Nazism, the current mass roundup, incarceration and brainwashing of Muslims in concentration camps in China's northwest would provide a much closer analogy than one young man freely expressing his opinion in the FCC. But that is being done by the very government for which CY is such an ardent apologist, so we won't hear a word from him about this particular egregious abuse of human rights.
A third irony is that the pro-China camp's heavy-handed attempts to derail Andy Chan's planned speech reinforce his assertion that Hong Kong can only enjoy true freedom outside the suffocating embrace of the motherland. While most of us don't regard Hong Kong independence as either likely or practical, those most determined to prevent it are inadvertently strengthening the case in support of it.
