I obviously have a very different viewpoint about this topic. I do not at all see sarcasm or anger.
Don’t feel alone - I’m with you on this, lj. I watched it over and over, and now a few times more, to see what I was missing. I can’t spot anything insincere in either Miller or Pence in that clip. Granted, it’s hard to read masked facial expressions, but even freeze framing and copying images to zoom on Pence’s eyes didn’t read “anger” to me. Perhaps someone will explain how that impression was reached.
