While the black callers to C-SPAN may be reading from a script, you made one outlandish statement here. What do you mean "they're not smart enough to be watching C-SPAN out of pure choice?"
If it isn't from a "being Black" point of view, they have no point of view.
If you disagree so be it. But that is my opinion based on what I've heard and why I no longer watch C-SPAN. It ceased to be as enlightening as in the past.
