You believe that things only happen to people because they don't "speak up" but it is a goofy belief. There are people that will first fire you, then hit you with sticks and jail you, then shoot you and your kids.
You are not the first person to complain. There is no manager to call. Standing in the street with your friends is a social event. If you're not telling people where and when to show up, what to bring, and why it will work, you're just on the internet stealing valor from real heroes.
If something similar were attempted in any Western country, the people involved would be murdered and things would be back to normal the next day.
There’s a reason European countries maintain twice as many police officers per capita as the “police state” China.
