Unfortunately there are businesses that contractually obligated to do business in Berkeley. Instead of trying to boycott every business why not target your boycotts to businesses that support this anti-military mentality and strongly support those businesses that fully support the military. It would be unfortunate to boycott and inflict financial damage to the Mom and Pop business that supports the military. Show your support for these pro-military businesses with your pocketbook.
Berkeley has been the hippie haven for a long time now so as far as I’m concerned any business in Berkeley is fair game. There maybe businesses in Berkeley that support the military and it’s unfortunate if they get financially hurt for being in the wrong place at the wrong time.
