Hello Xavier"  The best measure of one's comments is the comments themselves.  Ms Harris, indeed, expresses that she once felt the KKK was "limited to the South."  She adds that, through personal experience, she found that was not the case.  I think it's a bit of a stretch to call that "prejudice against the South."  Believing the KKK was only active in the South was mistaken...Ms Harris openly acknowledges this ..."dumb me."  With that statement she admits she was wrong.  The ability to acknowledge ignornace (lack of knowledge) and change one's view is the antithesis of prejudice.....and that is just what Ms Harris demonstrates.  

I cut and paste definitions to remove "my interpretation" from the meaning of words....  not to "promote" them.  

wishing you a pleasant weekend.  Gary crum
