Condemning a show because it's about Muslims is ridiculous. There are Muslims and then there are Radical Muslims. That's like judging all Christians based on the KKK.

That said, Lowe's is a corporation that acts under the direction of its Board of Directors, who are appointed to carry out the wishes of its shareholders. If the shareholders want to do this, and they are willing to live with potential consequences of lost sales, boycotting, etc., then they have every right to do so. They shouldn't be forced to advertise to a demographic that they believe won't shop at their stores.
