Human rights violation by china are well documented. You can look them up yourself assuming you have access to an uncensored internet. I cited disappearing people as the example that I thought was most relevant for the extradition bill.
The triad attacks are definitely real (we are in the age of smartphones after all): https://www.bbc.com/news/world-asia-china-49071502
I don't think you realize how much the difference in cultural values is making it hard for us to communicate here. Westerners consider what you call "violence and destruction" to be a fair price to pay to have rights guaranteed. Fighting is necessarily ugly but shining laser in eyes is laughably tamed compared to the lengths democratic societies have historically gone to protect their freedoms.
I do understand that some people just want to go on with their daily lives and ignore the atrocities going on in the background as long as it doesn't happen to them. I am not even arguing that's necessarily wrong either, just very different from western thought.
