Clay Risen, author of Red Scare: Blacklists, McCarthyism, and the Making of Modern America, joins to discuss the era when suspicion was a political tool and civil liberties were sidelined. Today we have echoes—and outright repetitions—of McCarthyite tactics, from loyalty oaths to immigration crackdowns. Also- there may be three plastic spoons' worth of microplastic in the average human brain—according to science, which Mike neither trusts nor understands, on account of his 0.5% spoon brain.
