If nothing else, Lee was dishonorable in standing with and fighting for the traitorous confederacy when he could have led the Union army and brought far greater honor to his name than that very considerable amount which he had already accrued and subsequently squandered. He was against slavery and secession, but still chose to stand with traitors. A bad call of historical proportions.
All that having been said, these 'students' likely knew all this before they even applied to the college so they are probably just trying to pad their 'lefty' resume in preparation for careers as douchebags upon graduation, should they get that far.
No, Lee was not 'traitorous'. Lee stood for what was right and for how the United States was set up.
The States created the Federal Government to serve the States, not for the States to be subservient to the United States Government. The States were to remain Sovereign in everything except in the powers specifically granted the Federal Government by the States via the Constitution of The United States. No where in the Constitution is the Right to Secede prohibited to the States, therefore the Right to Secede remains with the States. Add to that the Declaration Of Independence and it's clear, the States were within their Rights to secede from what they saw as a tyrannical and oppressive Government.
Asa May, one of the largest Planters in Jefferson County Florida was secretly schooling his 'slaves', whom he chose to call his 'people', to read, write, and do basic math to prepare them for eventual freedom. He inherited slaves and was never comfortable with the idea of one man owning another. Ending slavery wasn't as simple as just telling slaves, "Hey, you're free, get off my property or pay rent". Many suggestions were offered by slave owners as to how to peacefully end slavery. All were rejected by the Northern controlled Congress to placate their radical abolitionist supporters, and to keep the money coming into their campaign coffers from the rich textile mill owners.
I'm not denying there were hard core slave owners who were against anything that freed any slaves, but that it was more complicated than just suddenly freeing all the slaves to survive on their own. Reality is, the way it was done led to 100 years of conflict that is still being experienced today in some places.
Spin it any way you choose, it was a National disaster caused by politicians. You can not polish a turd, and turds are all politicians produce.
