Complete rubbish.

Slavery was a part of the Confederacy just as it was part of the Union.  Lincoln stated clearly that he would rather have slavery and keep the Union, than have manumission and not keep the Union.

You lend new meaning to the concept of "ignorant arrogance."  Lee's will freed his slaves and he was against the institution of slavery.

Whipping was a common punishment at the time.  Freemen as well as slaves were frequently whipped.  Andrew Johnson was frequently whipped as a young man for his misdeeds.

When the Army of Northern Virginia invaded PA, they did not rape, steal, vandalize, and murder civilians as the Yank armies did throughout the South.  Their civility was due to Southern commanders like General Lee.

Sic semper tyrannis!
