That's a very good point.
One of my many frustrations with them is that they're so damn poor at articulating, well, pretty much anything. All I get are talking points, shallow platitudes, and personal attacks. Zero (0) original, independent thought. So I can't get a solid handle on the why of anything. It's like they think they're doing a talk radio show, 24/7/365.
One thing about which I'm sure: I can articulate their points better than they can.
I get little hints and clues here and there, and I get a bit more in real life because seeing facial expressions is very helpful. Here, though, holy crap. So the value here is in basic observation, as if I'm in a lab.
