I'm not that far out of undergrad, and in my capacity as president of the political science society at a fairly large university, I dealt with moderating actual debates and collaborating with political clubs and organisations on campus like College Dems, Reps, DSA, TPUSA, YAF, etc. Having attended and co-hosted many substantive events across the political spectrum, yes, I can say these kinds of debates and this brand of guest speaker in particular are pure spectacle and cheap point-scoring. Anyone with experience in this ecosystem will tell you the same.
