Another lie to make an excuse for war. The south lost for Gods sake, move on. And school books shouldn't be northern or southern, they should be the truth.
  In the minds of many, the south lost because they were fighting for an unchristian system.
 As it's always been, if you only want your version of the war told you better win. You will notice the General didn't deny that the south was .fighting to retain slavery. What he said is that the north wasn't fighting just to abolish slavery. 
 Have a good life amvet, but know that there are a lot of us old folks from the 60's who saw the truth with our own eyes when it come to civil rights of then and today. You won't be able to smother the tragic truth in down home charm or your humble talk of Christianity.
