You didn't read the post, did you?
Benedict Arnold's behavior has not been accepted, but his character is better understood, and he has benefitted from a certain amount of historical revision.
His talents as a commander and his genuine heroism early in the Revolution are better known now, for instance. His bitterness and his wife's involvement leading to his betrayal of the Patriots is better understood.
It benefits no one interested in the realities of why things happen to brand historical figures and then to dismiss them. Understanding benefits historians, and branding benefits propagandists.
