I read his article. He is right, San Francisco has severe, unbelievable problems with homelessness and drugs which are so painfully obvious to anyone who has ever visited I felt like I was reading something out of the twilight zone.
I hate the climate of hostility towards anyone who remotely points this problem out. The reaction and tone of this article is exactly why I hate looking at Twitter now. It has become a platform for lecturing and shaming other people for stepping out of a very oppressive and narrow range of opinion or expression.
I now find articles like this and these daily recurrent societal witch hunts to be infinitely more offensive than anything this guy wrote. I don't want to live in a self imposed culture of toxic silence so no, Hacker News, I will not join in with your witch hunt and participate in group shaming of some random guy who wrote a bad letter.
