Apparently it’s no big deal to severely offend an entire religion. GOP presidential candidate Rick Santorum on Sunday criticized President Obama for apologizing to Afghans this week for the burning of Qurans by NATO forces at a U.S. military base. “There was nothing deliberately done wrong here. This was something that happened as a mistake. Killing Americans in uniform is not a mistake,” Santorum said during ABC’s This Week. “Say it’s unfortunate … but to apologize for something that was not an intentional act is something that the president of the United States in my opinion should not have done ... I think it shows weakness.” He’s not the first to slam the apology: Newt Gingrich and Sarah Palin were both critical Thursday.
