@pschwede I was born and raised in Hong Kong for 15 years pre-1997. Hold your horses on the idea of just giving out UK citizenship for free.

Like @freemo said I appreciate the sentiment of this intent. I wouldn't mind having the option of UK citizenship myself, but there's one thing I want to point out in addition to what freemo said:

HK rioters are fighting for HK. A citizenship elsewhere means nothing to them, if HK itself cannot be protected. My brother is living in HK right now and, while not actively rioting, refuses to leave even though he has permanent residency in Australia.

Considering the power China holds over the world right now, I don't blame UK only resorting to "virtual signalling" - they're doing the best they can. Handing out citizenship for free is not a gesture of care, when the one thing that HK rioters really want is not to live somewhere else better, but to save their own home.
