Lee of the traitorous Confederte States
Lee, of the traitorous Confederate states, was not a good man nor a good "general*". I'm not saying this because I hate Lee (I do) and just let that blind me, plenty of awful people were good leaders (side eye Napoleon) but Lee was neither. The only reason people claim otherwise is to laundry the traitorous racist Confederate state as something other than it was by trying to find a "good" person or a "good" leader.
*He only ever was a Col in the USA Army
Fuck the Confederate States of America and all of it's supporters.
