If you're gonna go pro-colonialist might makes right, that's your prerogative, but then you're just gonna have to eat it on the fact that the PRC had a lot more might nearby.
Giving HK back to China is an act of decolonization. Putting them under Taiwan and loading up the island with US weapons would not be.
PRC is itself a colonialist power. See all the Uighurs in concentration camps.
I don't want to devalue your experience, but Anglo powers have a terrible record of "colonialism for their own good", "we'll be greeted as liberators", etc.
