Wal-Mart Hit by 'Brokeback' Protest
Wal-Mart has turned aside a massive letter-writing campaign by the American Family Association urging the retailer to refuse to stock Brokeback Mountain, being distributed by Universal Home Entertainment. The group, which has successfully campaigned against what it considers to be broadcast indecency launched the campaign last week after ads for the film began being displayed prominently in the retailer's 3,900 stores. In an interview with today's (Tuesday) Los Angeles Times, the AFA's Randy Sharp, accused Wal-Mart of helping to push the "gay agenda" by "trying to help normalize homosexuality in society." He added, "But how many copies are they going to have to sell to [recoup] the losses of customers who they've offended and will no longer shop at Wal-Mart?" But a Wal-Mart spokeswoman replied, "The fact that we are offering the movie is not an endorsement of the content of the movie or any specific belief. ...We simply offer the latest titles that consumers want."
p.s. the afa is a nazi-esque organization and has failed several attempts to intimidate major organizations for promoting equality, most recently their failed boycott of ford for advertising in gay publications. in other words, it's just free press, the only threat here is to the afa making themselves look like even bigger idiots, as if that were possible.
