re: Myth of Robert E. Lee: Legend of Robert E. Lee's heroism and decency is based on fiction

Serwer has posted a long response to the National Review's response to the original column. It's worth reading. I'm curious which of these items the Lee cult/apologists characterize as untrue:

quote:

---

McLaughlin does not dispute that Lee was a cruel slavemaster who engaged in dubious interpretation of his father-in-law’s will to maintain possession of his slaves until a court ruled against him; that Lee betrayed his country in defense of slavery; that Lee turned a blind eye to the massacres and humiliations of black soldiers by his subordinates; that Lee kidnapped free blacks and returned them to slavery during his invasion of the North; that Lee publicly opposed the rights of the freedmen after the war; or that Lee, as president of Washington College, turned a blind eye to his students engaging in racist terrorism while punishing them harshly for trying to take extra time off on Christmas. Indeed, McLaughlin concedes, “Lee was no hero; he fought for an unjust cause, and he lost.”

I've bolded two that catch my eye in particular. On the first, what conceivable "noble cause" was that done in service of? LINK
