For starters, I don’t recall seeing a single white individual in the half time performance… racist much? Oh wait… it’s only racist the other way.
Second, the performers all dressed in white seem to be implying a lack of diversity… everyone the same and nobody stands out other than, obviously, the one performer… almost like a one world order.
Third, those white outfits almost seem to imply an astronaut/space suit attire. Why? Maybe prepping masses about aliens or something?
Finally, all those dressed in white all seem to portray NPC’s.
Edit: with that many performers, there seems to be a lot of lockstep and coordination between them… maybe something about compliance?? Get in line and do what you’re told like everyone else?
These are just my observations
The white outfits reminds me of HAZMAT
