Legally, or technically, or something anyway, you’re wrong about Benedict Arnold. At the time, the United States of America didn’t exist, so he couldn’t actually betray it. One might describe Arnold as a loyalist and Washington et al as the traitors. But that would be wrong too, because a rebel is different from a traitor. That’s also why the commenter who accused the Confederacy or treason was incorrect. Again ,that was rebellion, not treason.

Much depends, of course, on who won the argument, or how the various nations perceive themselves. The Confederates are only rebels because they lost. Arnold is a traitor because you got your independence (and if Washington had foreseen Trump, he might well have surrendered).

Did anyone else ever notice that in LOTR, the orcs refer to Men and Elves as ‘rebels’?
