Is There Anything Liberals Won't Start Boycotts Over?

It seems like every time I visit a liberal website, someone's calling for a boycott of some business, state, or organization due to a slight against some facet of liberalism.  Over at Feministing, they wrote last week about a boycott of Old Navy by "breastfeeding activists" (aka "lactavists") who are angry because they sell baby clothing with "Formula Powered" printed on it.

No, I'm not joking.

Ever since the boycotts and sanctions helped to end apartheid in South Africa, liberals have gotten the idea that boycotting is an effective tactic against anything that offends them, no matter how trivial.  And it will continue to be an effective tactic until people are willing to stand up to the political correctness at the core of liberalism.
