I know he liked to publicize the exchanges where he got the best of someone, and bury the others, and that he was a far, far cry from a public intellectual. Still, he talked to folks about ideas, and that's something that we should have more of.
That should be something that we strive for, but I fear we'll see it less and less. Who'se going to want to go around and argue with people now?
So if you want to engage people politically via debate, then university campuses are a good place to do that and thus - to someone extraordinarily uncharitable - any such debate could be described as "trolling immature leftist college students to score YouTube views". The same activity done by an academic would be described as "presenting the youth with mind-expanding dialogue", and they'd be doing it to score tuition fees, but nobody would quibble with that phrasing.
Debates are not two parties seeking the truth together. Unless you're very, very careful and good faith, and your counterpart is very, very careful and good faith, debates are a race to the bottom of psychological manipulation. They're not contests of facts; there's no way to objectively score them; they're not good ways for participants or bystanders to learn.
Facially, they're theater. But a system's purpose is what it does, and these performances serve as a venue/foundation to hone/push messaging. You'll almost never see right-wing "debaters" go up against "big" left-wing names like an Ezra Klein or Destiny (Ben Shapiro is kind of the exception, but he's far more conciliatory with someone like Klein--he did do one with Destiny, it went pretty badly for him, so it of course became a one-time thing).
Kirk et al lose--they lose frequently! You rarely see it because they have far bigger megaphones than their victorious rivals. But have these (many) losses changed their views? No. Debates are not two parties seeking the truth together.
