Perhaps one should remember that General Lee did not start that war. Like millions of others, he was drawn into it by several factors not under their control. Like the others, Robert E. Lee was fighting for what he believed in and that was and is an acceptable endeavor for that time. In my opinion, your comment is caustic, ill advised and belligerent. That being said, I suspect that Robert E. Lee, had he heard it, would defend your right to say it and forgive you for having done so.
He, sir, was a gentleman.
A ‘gentleman who waged war on his own country? A gentleman who fought a war so Southern plutocrats could maintain slavery? Jeez your stands aren’t very high.
