San Francisco has for a long time been a cool city of, like, far out hippies and other artist types. Now it's filled with PC police who shame you for your "offensive" jokes or if you eat meat.
James Hetfield of Metallica eats the most organic food possible (he's a hunter). The people of the Bay Area would shame him for being a hunter so he GTFO and moved to Colorado. He lived in the Bay area for like 35 years.
