I have asked her about her emotions and feelings. To quote her. She says that she hates the Chinese. She hates China and all people living there. She feels that all actions that are linked to the Chinese government (such as the current law) are an attack on her country. Thus, she is posting a lot of biased and super heavy crap on social media these days and is full of hate against the police (who are ironically also Hong Kong people, but she does not care).
What we see there is just a terrible eruption of anti-China emotions. People need to vent.
Ironically, my girlfriend is also blaming the "rich Chinese" who are "coming to HK and buying all property, which prices out HK people". At the same time, her family owns X apartments in HK and in mainland China.
