America is vastly (by multiples) better than the Muslim world for reasons far too many to post...
It's rather myopic to take one evil aspect of American Culture (abortion) and apply it across the board as a comparison, when there are literally thousands of comparisons where we can make that are far better the Muslim world..
Who was worse: Nazi Germany or Stalinist USSR?
If one believes abortion is murder, that “one evil aspect of American culture” makes us far worse. There is nothing comparable in the Muslim world, only in the worlds of Hitler, Stalin, and Mao.
