How come nobody cared about 'universal human rights' for HK residents until it was a way to kneecap China? Again, check the record: 95 years of colonialism with less rights than they have now. They got their limited democracy in the last few years of British rule. Thatcher and Reagan never gave a shit.
Watch their hands, not their mouths, that goes for all politicians.
Xi has a lot of problems in general on the rights front, he's moving things in the wrong direction, but we have no leg to stand on regarding HK.
