I agree the core of the problem is not in the gun control. As you say school shootings in US skyrocketed in last 30 years but as far as I know the amount of weapons didn't change significantly. Gun control does make these attacks harder though so I don't think it is necessarily a bad thing but it is in my opinion a similar kind of band aid as the "warning system" this article was about. As an example we had school shootings in my country (Czech republic) as well where the gun control is strict and we had also stabbings by knife etc. The real problem is kids want to kill other kids, not the access to weapons. I think a big problem here is a media coverage which makes hero out of the murderer - you get to headlines of all the news, there are analytics papers about you, heck even several years later there are news articles reminding what you did - you are famous! And in our society where success and publicity is above all some poor souls pick this as a shortcut to fame and lot of them actually openly admit they got inspired by their predecessors. Plus there is influence on subconsciousness where killers in movies are depicted as cool and great, even airgun athletes from Olympics where presented in media as cool hitmans and this all promotes the idea that killing will make you cool.

All these big companies do censorship - Facebook, Youtube, ... And it is not only to be able to operate in China, they censor stuff some people e.g. in US do not like. For example Youtube recently deleted multiple channels of Creative society talking about various climatic disasters with eyewitnesses and how broken our system is when most of these people are left without any help after a while, or how refugees camps are maintained in third world countries as a cheap source of organs for transplant, or how World bank puts third world countries into huge debts so that western corporations can get cheap control over their mineral resources. Sure these are tough topics for our western society but staying silent about them is going to make things worse not better in my opinion.

Yeah, I agree that only if enough get sick of the current system (and it does not matter whether in China or in Western countries) and if they actually start acting, then the system can be changed. So far I find a lot of people see the system is sick but they're afraid to make a change. For this I like Creative society project how to change the society - it may sound idealistic but to me it makes sense and these people are willing to act to make a change.
