Should Lowe's need a crowbar to pull its head out of the sand, it can find one in its own aisles. On Saturday, the home-improvement company posted a note to Facebook explaining its decision to capitulate to an email campaign by the Florida Family Association and pull its ads from the TLC reality show All-American Muslim. As of this writing, the post has drawn more than 22,000 comments, a significant portion of which are racist and contain anti-Muslim/anti-Islamic hate speech. (Scroll down to see some of them.) So, why isn't Lowe's moderating its Facebook wall?
