The
far right was able to start misrepresenting the Civil War late in the
19th century: it was about states' rights (to create
insurrection/war/treason against one's own country) not slavery...
Except that each seceding state created a new Constitution that featured
a white person's right to own black people as slaves; recover and
punish any slaves that might have escaped.
Two
terms of an African American President and minority-majority (white
people as the largest minority, where all the other races total a
majority of the US population) drove the crazy, insecure, white
(northern European Americans) out of what little sanity they retained.
If
the right, wing nuts lose this round of a combat free, re-prosecution
of the Civil War without consequences (investigation, documentation,
indictment and prosecution in a court of law) they'll be back, again, as
soon as they can regroup.
