Considering it’s a back the blue flag, I’m going to guess they’re making commentary on modern white supremacists. Neonazi openly flew the nazi flag in the 80s and 90s, then when that became too niche they moved to the confederate battleflag so they could dogwhistle a bit, then moved to back the blue once the dog whistle became too obvious amongst the general population (as if it’s fooling anyone anyway)
I think it’s referring to the people that fly the confederate flag in the current day not the actual time period it was used.
All of those flags are still flown by some people, but I think if we’re talking root causes it would be more informative to swap those two.
