But the same is true everywhere though. You think that Houston or St. Louis or wherever don't "adopt behavioral patterns" to make themselves feel safer too? Only SF residents are smart enough to make life in the wasteland possible?
No, that's silly. SF isn't unsafe, period. SF residents (specifically ones right here[1]) "feel" unsafe because of an out of control meme. And now it's leading this formerly rationalist and clear-thinking demographic into these ridiculous rhetorical holes.
Cities are cities. They've always been like this. If you don't like it that's fine, but please stop pretending that anything happening in SF is new, or unique, or special in any way. It's just what your microcommunity has decided to yell about this year.
[1] Which doesn't include me. I'm in Portland, having lived in SF previously and grown up in the urban northeast. Cities, again, are cities.
