Oh, wait...
I recently had to make a couple of brief trips to San Francisco where I hadn't been for a long time. I was a little surprised that in all the people I ran into there, there were only one or two that seemed obviously gay. I did see a significant number of drunks, people on drugs, mentally ill, and/ or homeless, but perhaps no more than in many larger cities.
Overall the city seemed to be a lot more prosperous than I remembered. It actually is a pretty attractive city, if you can afford to be there. Maybe that is one reason why there are undoubtedly a lot of gay citizens, but that is not all that San Francisco is about.
I live in the Bay Area! All of San Francisco is not bad! I know plenty of conservatives and Christians that live in the area.
