So, why don't you get a group of conservatives to go to the SF city hall with your pets, lamps, grandmothers and favorite blankets and demand marriage licenses also? If enough people showed up trying to "marry" their "life partners" of different absurd extremes, maybe the officials would begin to see the problem.
To really give 'em a slap of reality, I suggest going down to SF City Hall and lighting up a Marlboro....since laws are now apparently a non-starter up there.
