Hi La Lucha, don't waste you time trying to get through the thick skulls of sexist men and their Barbie Cheerleaders (men's little helpers).

Here are their standard responses:

1.Sexism is cute and OK if "the artist was a woman" (so by this "logic" opposing affirmative action is OK for blacks since a black man opposes it -Clarence Thomas)
2. If you object to anti woman sexism you are a "humorless feminist" aka "What's the matter cant you take a joke?"
3. white men are oppressed too
4. Sexism is "art"

You have the right idea. Boycott the brewery and encourage your friends to do the same.
