Destruction and creation are a-symmetrical. I had an interesting exchange with another HN'er not that long ago about that very topic. I ran a community of a million people and it took by my estimates less than 50 dedicated assholes to totally wreck it for everybody else. How they managed that and why I couldn't stop it is very much related to how 'open societies' are impossible to defend against a large enough number of idiots hell bent on destroying them. The ease with which you can destroy something has absolutely no bearing on the amount of hard work it took to create it. Societies are no different in this respect.
In my years and travels, I've settled on the fact that the only solution to those "assholes" that destroy community fabric is overwhelming force. You cannot reason with someone who has nothing to lose.
Unraveling of complex systems is very interesting discipline. We are so fragile. And we intentionally put resilience at the bottom of the priorities. Right now Europe needs people that refuse to be intimidated and simultaneously do not turn into bloodthirsty fiends. But we must have began the process of instilling said culture a decades ago.
