I would argue that Robert E. Lee was for the following reasons: 1. He rejected his US citizenship in order to join a rogue terrorist nation(little known fact, he lived out the remainder of his years on parole and never was given his citizenship back during his lifetime). 2. He burned American flags and fought under a terrorist nation's flag. 3. He fought to preserve the evil institution of chattel slavery and was a HUGE proponent of slavery. 4. He murdered hundreds of thousands of American soldiers, more than Hitler, OBL, and Saddam combined. 5. He encouraged and led hundreds of thousands of former Americans to join a rogue nation and fight for that nation against the USA. IF anyone can name a bigger traitor with evidence attached, I would welcome it.
