There are genuine voices out there who disagree with the protestors political aims and who completely reject the violence employed by a radical minority of the protestors. Not everyone is a "wumao" or "5 cent" paid troll or bot.
It would be nice if there were more critical analysis of the Hong Kong protests. For example, why do prominent faces of the movement such as Joshua Wong frequently use the phrase "God Bless Hong Kong" for Western media interviews (and in a congressional hearing yesterday)? It's a phrase completely alien to Hong Kong and Chinese culture and clearly pandering to a target audience.
