Earlier quoted context omitted.
The US has a fairly high tolerance for weirdness and novelty in general because of its extreme fixation on individualism. Especially so when you compare it to most other high income countries like Japan, Germany, Norway, Switzerland, etc.
People say that a lot but I'm not so sure. Half of my American friends had to move to the SFBA not just for a job, but because nobody understood them back home, or they'd be literally persecuted for being who they were. And these aren't always tiny rural towns. The coastal cities embrace some kinds of individualism for sure.
If it's a majority, then I think it's safe enough characterize the individualistic attitude as American.
