Do you still beat you wife?
Actually I am for secession and think it was totally legal.
Do you agree with Lee or Grant about slavery?
Secessionism is no longer a valid point of view. The issue was settled with blood. You should understand why the vast majority of Americans view the flag of rebellion and secession with repugnance.
As for what Lee or Grant thought of slavery, who cares. The Union was preserved and slavery was abolished.
