I just think it is the job of us liberals to call out behaviors that are morally unacceptable no matter what their ends are. A salient feature of this movement is the joining force between moderates and radicals (I recommend CUHK professor Francis Lee's Solidarity in the Anti-Extradition Bill movement in Hong Kong) and a peculiar absence/silence of the political left. Outpouring admiration for Lee Kai Shiang and targeting the MTR (used by lower and middle-class HKers like myself) tell you where things have gone wrong.
