I'm not in favor of glorifying the confederates, yet just because you don't like something, it's ok to justify the means of removal?  You are the decider of good and bad?  That's quite a honor you have given yourself.  What are your views on the Pyramids of Egypt?  They were built with slaves, should we boycott Egypt due to racisim or whatever basis they used to decide who were slaves?  There are hundreds and probably thousands of monuments globally that were built by slaves.  Should we ban pictures of those in our books?  Should we protest their existence?
