I had no idea what it meant (I assumed it was something picked to be generic and inoffensive, like Tennessee Titans) and was pleasantly surprised when a shitposter on Twitter I follow RT'd something about it. The reference is actually to the
Guardians of Traffic, big-ass art deco statues in the city.
To the question of whether Lee at al were traitors, here's a simple acid test: given that they lost the war, were they hanged for treason? No? OK, shut up then. It's not like people had great compunction about executing traitors in the 19th century, and given the Confederacy's unconditional surrender, it would have been child's play to pull off. OFC, that never happened because the entire "reunification" narrative that the Union used to legitimize it's position was that the war was a tragic misunderstanding within a nation- a "brother war" if you will- and that the South was being re-integrated, not conquered. Whether or not this is bullshit is an exercise I leave to the reader, but the point is that we've gone over a century and a half without considering the Confederates to be Benedict Arnold-tier traitors, and trying to retcon them into that now is complete bullshit, especially in light of the actions of the people who were actually there.
