I support "Generic School Name."
Either that or keep it as it is. While Lee was no marble saint, he was the best general of that war.
However, contrary to general opinion, I'm glad he sided with the South. If he hadn't, the Confederacy would have collapsed in 1862, the South would have been readmitted without emancipation, let alone reconstruction, and there would have been decades of guerrilla warfare in the South, quite possibly leading to a Second Civil War. Sometimes a long bitter war is what is needed to clear the air, and that is exactly what the American Civil War was.
