The Catholic League is calling for an extended boycott of Miller Brewing Co. because of its sponsorship of the (graphic) depravity that is the Folsom Street Fair. As a prudential matter, as nearly all boycotts are, Miller's sponsorship of the event did not seem to have been provided expressly to support the behavior featured on display, making the proximate relationship to evil of a purchase of Miller products second-order at best, assuming it is also not intended to support the event.
Another thing is there is really little choice if you are craving mass-produced light pilsner, which, yes, I do on occasion. A friend of The Clan's has been boycotting Anheuser-Busch for several years because of their sponsorship of similar events, though not quite as over-the-top as this one, in other cities.
In fact, these kinds of things (boycotts) can only have a snowball's chance unless they somehow affect the unholy alliance between professional sports and the alcohol industry.
That said, I'm certainly not going out of my way to buy Miller, but neither will I be pouring any down the drain.
