I'm a "northerner ".  When I was 21 I moved to Virginia to teach school and was astounded to learn that the War Between the States was anything but over !  
Just about every battle fought spilled blood all over the South  .  Both southern and northern blood to be sure  .  However it was for each side a rich man's War but a poor boys ' Fight .   Moreso for the Confederacy  .  
I say this not to excuse horrendous behavior  .  Rather to stress the depth of the evil which continues to engulf our entire country .
Unscrupulous individuals use this repeatedly for their own purposes .  
Treason ?  In an age of States ' Rights ?  150 years ago ?  And why , right now have we seen this same disrespect for the Central Government  ?  And dare not call it Treason ?  
We don't have the luxury to live in the past .
Failure of Education , Decent housing , Proper nutrition , Job Opportunity,  Safe streets is destroying all of us .  We will only put an end to Racism by addressing its roots .
