> Also this guy wasn’t dangerous. But in the moment you don’t know that. What you do know is this person is obviously not acting in an appropriate manner consistent with the expected societal norms for pretty much everywhere in the world except SF. That means they may be more capable of other behaviors outside the norm and that makes them dangerous. That’s enough for most people to be put into a defensive mode in that kind of encounter—causing people to feel unsafe during an encounter that may ultimately just turn out to be annoying and inconvenient.
