Miller Light is my favorite beer. Actually, it's one of the few beers that I don't dislike, but I'll be switching to cocktails when I do my social drinking because as of now, I'm boycotting Miller (link from The God Fearin' Forum). Two things about this: first, Miller's offense isn't just against Catholics. The Folsom Street Fair is an open and public celebration of sexual libertinism. It is the focal point of the libertine efforts to push the boundaries of what is socially acceptable. By supporting it, Miller is funding an effort to expand those boundaries. I think the boundaries have gone far enough already, and Miller won't be using my money to push them further.
So, sure, it's going to be a little awkward when all the guys are having beer and me and the chicks are having margaritas, but on the bright side, I really like margaritas better anyway --on the rocks, with salt on the rim. Out here in the Bay Area, you have to actually ask for them that way or they might give you one of those headache-inducing frozen concoctions with no salt. Some of these barbarians even put fruit in their margaritas and make it a sweet drink. It's almost more than an old Tucsonan can tolerate.
By the way, the Folsom Street Fair was the occasion for number 7 in my list of things that I've seen in San Francisco that I never saw in Tucson. I had no idea what was going on, just that a bunch of men were wandering around the streets in leather thongs and vests. This wasn't in an isolated area, it was spillover from Folsom Street to Market where innocent tourists were wandering around with their kids.
