Self-deluded Hong Kongers can always find ways to justify the West and at the same time demonize China. They are not being called a lost generation for nothing. Hopefully, they would never return back to HK. Many Hong Kongers in Taiwan, Canada, and the UK would be forced to go back China after a few years due to deterioration of living standard.
Even if they do not go back its fine for China. Cause they will become potential recruits as future Chinese spies or pro-China crowd supporting China. Plenty of ethnic Chinese migrants who hated CCP 20-30 years ago are very much pro China now. Their delusions about the west slowly eroded away, their self-hatred about being ethnic Chinese also slowly faded. Racism they faced was also a big factor in such transformations. Plenty of foreign born second generation ethnic Chinese are also heavily Pro-China due to these reasons.
Look at Malaysian Chinese now, because of all the discriminations they face, they are one of biggest pro-CCP Chinese abroad. I think Hong Kongers who leave now will change their minds in 20-30 years just like how many Tiananmen protest participants became heavily pro-China later on.
