BRIANNA KEILAR: When Tucker Carlson was arguing against the renaming of military bases named after Confederate generals and against the tearing down of Confederate statues, he said, "A country is the sum total of its history, good and bad." He said, "Eliminating the past leaves us unable to say who we are." Well he's trying to eliminate the present, and he is spoon-feeding it to millions of hungry viewers who tune into his show. "Healthy societies do not destroy their own history," he said last summer. But what he didn't cop to is he is that part of the illness, a propagandist, a liar, a parasite.
