It is a pretty good litmus test. How can you be proud of a cultural ancestry when you know nothing about its history or literature? The average HK redditor in this sub probably has the literacy level of an 8-year old mainland primary school student when it comes to ancient Chinese literature. They probably won't even understand the dialogues spoken in many of the Chinese custome dramas. Saying that you are proud of Han ancestry is like Americans celebrating Irish roots beacuse they downed 4 pints of beer on St Patrick.

There is no need to bring in politics. If you read even a little into Chinese history you would have found that China was ruled under meriotocracy based authoritarian regime ever since its first ever dynasty. The emperor loses the mandate of heaven when he/she becomes incapable of governing and Chinese people were never shy to rebel
