They basically said they believe most people would hate it in San Francisco but that's the whole point. Because the people who love it there don't really fit in many other places. It's a sanctuary for a certain type of culture and that's where its value is.
Everyone deserves a place where they can fit in and for the young idealist, the aging hippie, and all the other odd balls that call that place home that's where they belong. But yes, as a consequence that means that a lot of other groups (most families for instance) don't belong. Not every environment has to be all inclusive.
