The two political parties that went to war in the Civil War still exist: the slavery party and the abolitionist party.  Those two parties, finally, are beginning to fail.  Good.  The slavery party is engaged in trying to further deny their history, as demonstrated when they thrashed around last year trying to change the name of their annual "Jefferson-Jackson Day" dinner, their equivalent of the other party's Lincoln Day dinner.  Their is no effort of the other party to eliminate their own history of being associated with Abe Lincoln.

So why should we deny the history as it exists?  Why do we try and hide the 250 million deaths, just in the 20th century, of people at the hands of their own totalitarian governments?  In order to not have history repeat itself, we MUST learn those lessons.
