Beinart detects one:
Even as public tolerance for most other forms of bigotry declines, hostility to Muslims has actually grown, despite the winding down of America’s wars in Iraq and Afghanistan. In fact, the rise may be partially due to the end of those wars. After 9/11, George W. Bush told Americans that although we were fighting “bad Muslims” (al-Qaeda) “good Muslims”—who constituted the large majority—would embrace our invasions.
It hasn’t worked out that way. My hunch is that faced with the realization that many Iraqis and Afghans hated America’s occupation of their countries, Democrats have been more likely to blame the U.S. for starting those wars in the first place. According to polls, large majorities of Democrats now see both Iraq and Afghanistan as mistakes. Republicans don’t. For Republicans, I suspect, America’s problems in Iraq and Afghanistan say less about us than about them. They prove that Bush was wrong: Most Muslims really are our enemy. Otherwise, why would they oppose our efforts to make them free.
