This is exactly a regurgitation of the propaganda by CCP. They blamed western influence, education and cultural whitewashing of HK Chinese as the reason for the current protests and their citizens believe it sincerely. They conveniently overlook the crux of the protest, which is to ask for universal suffrage.
Even for a well educated, widely traveled main-lander, it is difficult to come out of this conditioning. I have some friends from mainland, currently staying in HK, who sincerely believe the general public is too naive to be allowed to make any decision. With the right amount of conditioning, people can be led to believe in anything even if it is contrarian to their well-being.
