Are you an HK secessionist or merely seeking to delay / live out what was promised?
I.e., are you merely advocating for Hong Kong to peacefully continue the rest of its 20 years before full handover to China, under the system they've been used to? This is what was promised -- and you don't want China to prematurely erode HK's civil liberties?
Or are you seeking Hong Kong's independence, and a nullification of the treaty that was agreed to?
Because if you agree that the territory belongs to China, then we're just unhappy about it coming sooner than expected, right? It eventually would revert to China and have all the infringement of rights, which are now just being experienced sooner.
