Dan, I get your point...BUT, the caps were intended to distinguish the actual transcript from my own editorial comments. Since there's been so much discussion about what National Geographic actually said, it was important to me to be ACCURATE. If your sensibilities are offended, don't take it personal. Have a great day.
I certainly don't take it personally. I think it's just a law of human nature, as I've observed -- folks don't want to read all caps. It's considered shouting.
Your fundamental idea was a good one. In the future, to make sure you're better-heard, I'd suggest using bold for one, plain for the other; or italics; or you could even use red font.
One man's opinion, your milage may vary.

I used to work with teletypes.....everything was caps and I never felt I was being shouted at...
Actually, for my old eyes, the caps work well.
Then use quotes to identify the contents of the actual transcript.
A useful practice is to put quotes in italics, and your own comments in standard type.
