They have a fun graphic of people doing the Boston Tea Party with Miller Beer. (The original Boston Tea Party was done by men who disguised themselves as Mohawk Indians, which would now, I suppose, be considered worse than the underlying crime. )
I would be happy to boycott Miller, but I gave up drinking in 1982. From what I can remember, ( a little hazy in spots) it wasn`t much good either as a cool refreshing social drink, or for getting you drunk. You can sign a petition here, and you can check out Marketing Malt Liquor - and Shaping a New Underclass, for some insight into why Miller might want to encourage Hispanic immigration.
