The level of economy is the most important role to keep the politics stable. If you are at the level of Myanmar with the similar population as Britain, the situation will be very different.
This phenomenon of reverse nationalism only appear among the immature teenagers, and when they become maturer, they always become more patriotic. The reason of the phenomenon's appearing is that China is still not the most developed country, so someone may be not enough confident and suspect the justification of our political system(just like the phenomenon appearing in US before WWII). Other reason is the your western ideological infiltration, etc.
But CCP has handled the key to keep the country stable, it is the high employment rate and level of income. With the negative experience of democratization from Hong Kong and Taiwan, our people are enough sober. When China become a developed country once, there will be no this phenomenon. Do you agree with me, sir
