It looks like there are very different opinions about whether Silicon Valley culture is more or less tolerant than other places. However I think those differences can be resolved by viewing tolerance of background and tolerance of opinion on two different axes. In my mind SV scores very high on tolerance of background but low on tolerance of opinion (as in "we don't care how you look like, as long as you agree with our opinions"), whereas NY scores high on both, and places like Japan are the reverse (scoring low on tolerance of background but high on tolerance of opinion -- hope I haven't offended any Japanese readers but that was my impression when I lived there for a short while).
