Charlie Kirk may have been for debates he could win. And it’s the same as any radio show: vet the opposition first. You don’t even invite them until you know them inside and out. Turn their mic down and talk over them so they raise their voice, and turn it back up so they sound aggressive, then passively aggressively talk them down to gain the moral high ground. And if they start making sense, cut to commercial.

If all that fails, put them on a list and demonise that list.
