So somebody noticed the signal leaking out of the bubble.

But I think you're right about the lack of self-consciousness--they're in the bubble, its inner surface is mirrored, and as far as they can see, it's just us chickens in here.

This sounds to me like a textbook example of something we were talking about over on the OT thread: the existential angst of the centuries-old Southern white domination culture. (That phrase sounds awkward to my ear, yet unlike "white supremacy", "white domination" captures the emphasis on power rather than base racism. You don't have to dislike somebody to want to remain superior to them.)

The racism, while over-the-top despicable in the video, isn't really the dominant emotion among the southern branch of conservatism. What's eating them is the loss of white privilege and power. It's measured against other races, true, but, except for people like this individual perhaps, it's not overtly animus toward other races. This, I think, is why so many southerners can vehemently deny racism while speaking and behaving in ways we recognize as undeniably racist. The racism can be displaced nicely by blaming the Federal government for the diminution of their status.
