Unless you live in Oregon, and then maybe you might.
Looking over the Wiki page for the American Family Association thanks to this thread: http://boards.straightdope.com/sdmb/showthread.php?t=428725 , I discovered that they are/were organising a boycott of Nike.
Why, you might ask, would a conservative group oppose a company that makes sneakers?
Because the company came out in support of a bill allowing Civil Unions in Oregon. I can’t remember the last time I heard of a major corporation taking a political stance on something that didn’t directly affect their bottom line- other than withdrawing sponsorship from people who say something controversial, or whatever, which is generally done to avoid being the target of boycotts themselves.
Good for you, Nike.
