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.
