Singapore is overwhelmingly Chinese too. But there is a distinct and unique Singaporean Chinese culture.
The New Yorker is more like Shanghainese in this analogy. But I think in your reaction to my post, it perfectly illustrates the challenge between Mainland Chinese and Hong Kongers. You see them as just another Chinese, whereas they see themselves as more like Singaporean than Chinese. Chinese to you covers both ethnicity and culture. Where as the Hong Kongers are ethnically Chinese, but culturally distinct. Again. Think Singaporean . The difference is that Singapore wasn't handed back to China, whereas Hong Kong was. And here lays the conflict.
I'm not saying that "HK identity could only be preserved and maintained". I'm saying that HK has a unique and distinct cultural identity wether you like it or not. There's never a Chinese identity to reject. They never had a Chinese identity. Ethnically Chinese. Yes. Chinese identity. No. More so, THEY would like to preseve and maintain their cultural identity. It's not like they want to assimilate, and the CCP want to preserve their culture like some native american tribe.
Of cause the CCP's control is absolute and complete. We couldn't try to change your affairs if we tried. All I'm trying to explain, is that you feel the HK people betrayed you because they rejected their Chinese identity, when they never had a Chinese identity in the first place. There's nothing to betray.
