Somewhere between a score of 0 (America as the Great Satan) and 100 (America is Heaven and does no wrong) is reality. Paul simply points out reality - that we are not perfect and that we have done things to antagonize non-Americans.
This puts his opponents in a bind. They can't fight him on the other issues, so this is their one sad attempt to portray him as "lunatic." They do this by completely slandering him as "anti-American" (saying America does not score 100 is not the same as saying it scores 0). Ironically they only end up caricaturing themselves as a bunch of nut cases who think America is Heaven, a perfect land that never does anything wrong to anyone outside its borders. I see this many times each day on FR, so sensitive are the leftists here to Paul's message.
But his foreign policy and 9/11 views are wrong and very caustic IMO. He comes across a little like a cult leader and I have sometimes found it difficult to reason with his "followers."
Of course here on FR, there are cadres of "worshipers" of various candidates who seem to have lost a sense of proportion and reason. But I think by-and-large, people here are trying to think for themselves and find the best guy/gal.
