"...these people who were commemorated did not consider themselves traitors..."

That is very true, Rae.  But, traitors they were, none the less.  Throughout all of history those who rebel against the status quo never consider themselves traitors but, rather, heroes to their own cause.  In the case of the leaders of the CSA, they were for nothing less than the dissolution of the USA.  That is treason.  There's just no way around it.  I've said before that we should never forget the CSA and we should study it in textbooks and museums - - but it is never to be celebrated.
