In Philadelphia, a professor of history at Drexel University says administrators are supporting his right to free speech, after a satirical tweet prompted a backlash from white nationalists, who called for him to be fired or to commit suicide. On Christmas Eve, George Ciccariello-Maher wrote on Twitter, “All I Want for Christmas is White Genocide.” Ciccariello-Maher says the tweet was meant to satirize a conspiracy theory common among white nationalists. After the quote was picked up by Breitbart News and white supremacist websites, Ciccariello-Maher says he received hundreds of death threats. Drexel University officials initially condemned the comments as “inflammatory,” but Ciccariello-Maher says he’s been assured he won’t be disciplined.
