How is "knowing" synonymous with "ignorance" ? Anybody can consider whatever they want. For example, you may reside in the UK with British passport but consider yourself a Martian. Nobody can stop you from having an opinion. Whether everybody agrees with it is an entirely different story. A wish is not the same as fact. If you don't believe in Google, Wikipedia etc, then at least try the CIA fact book. But I'm guessing you"ll feel they aren't impartial either, since China and US have mutually-beneficial business interests. I won't. Since one is a city and the other a country. Hong Kong was always part of China before the Brits and Japanese took control of it briefly. So I don't think a Chinese guy living in Hong Kong will find it racist if somebody assumes he is Chinese.
