Hong Kong: mainstream media's choice

Learnedfriend wrote a citizen report in inmediahk.net comparing the two demonstrations he had attended and helped organized in the past few days (zh) ^[1]. One was a series of anti-war protests against the killing of innocents in Lebanon; one was an action outside Japanese Consulate, demanding compensation for the comfort women during WWII. The anti-war protests were better organized and many local people joined in; the latter protest was more an ac hoc action, with little mobilization and public annoucnment. However, the media attention given to the WWII action was four times more than the anti-war protests (with mainstream T.V news report team). He wondered why?
