HK never had autonomy.
They were controlled and raped by the British for British interests who conquered them with brute force and then they were taken back by China when Britain became weakfags and could no longer bully them.
Britain did try to give HK some extra "freedoms" in the handover as a poison pill against China just as the absurd Western elites now are supporting the protesters to fuck with China, they even oppose the mask bans which is funny considering most Western countries enforce them on their own citizens.
HK people are just mad that China is surpassing them and that they are no longer special boys and also that the turbo capitalist neo-lib system they are living under sucks dick and most young HK people can't afford to live a decent life in HK or afford an apartment bigger then a chicken coop.
Keep fighting for "democracy" AKA buttrape by global capitalists, oligarchs in exchange for meaningless degeneracy type freedom which empowers no one and grants you nothing.
