Fundamentally, people talking to each other on public video just doesn't strike me as such a bad, terrible, awful thing, even if it's about something you shouldn't have to debate.

The actual scenario under consideration in this case is "people talking to each other on BHTV specifically [1], about topics (such as creationism) that the relevant experts pretty much unanimously agree are nonsense [2], with people who refuse to debate (in person and in the literature) in good faith following the standard norms that govern intellectual discourse [3]."
