Romney was silent when George Bush made numerous statements more apologetic than the one he's attack
"In the eyes of Mitt Romney, Reince Priebus and other conservatives, President Obama committed the grievous sin of apologizing to violent Islamists when the the U.S. embassy in Cairo released a statement condemning anti-Muslim bigotry. (The statement was not an apology, did not come from Obama and came before the mob turned violent.) No matter how offensive the film was, it is protected by freedom of speech and any condemnation of it is nothing less than an apology for American values, Romney said.
Republicans, however, were willing to let similar statements slide when the guy in the White House had an R next to his name.
In 2008, a U.S. sniper shot a Quran in Iraq, causing an uproar. President Bush expressly apologized...
... Bush also personally and publicly rebuked anti-Islamic speech delivered by a top general, which sparked outrage among Muslims. Look, it just doesnt reflect what the government thinks, Bush told Muslims in Indonesia. Incidentally, that general, Jerry Boykin, is now an adviser to the Romney campaign and a top executive at the Family Research Council."
