I'mma chalk this up to Boots (and Spike) both being Late-40s and up. That generation didn't even make a surface attempt to do the whole Black/Entertainment Solidarity thing. None of those older nikkas seem like each other, from Spike to Singleton to Perry to Daniels etc. From what I've seen these dudes don't even really acknowledge each other, much less connect, collab and build.
If, for example, Klansman was just Peele and STBY was, say, Lakeith or Glover behind the camera, this wouldn't be happening. Those older nikkas are still playin' by Highlander, there can only be one rules.
At least that's how I'm seeing it.
