Then you must find the first sentence in the Preamble of the US Constitution "oddly curious".
Why?
Washington's decision to fight against the country of his birth was made long before that was written.
One cannot sensibly argue that Washington was a hero, while simultaneously calling Lee a traitor. They both remained loyal to a cause that they believed in and to a homeland that they individually defined.
Or I guess from the POV of those who feel that Lee was a traitor:
"One man's traitor is another man's freedom fighter"
