Gen. Milley has to be sensitive to the political realities in the White House, but he was clearly exercised about the criticism, saying it’s “important actually for those of us in uniform to be open-minded and be widely read.” He later added: “I’ve read Mao Zedong. I’ve read Karl Marx. I’ve read Lenin. That doesn’t make me a communist.” So, he asked, “what is wrong” with “having some situational understanding about the country for which we are here to defend?” Of course sailors and Marines should read widely. Chief of Naval Operations Admiral Michael Gilday said similarly last week that he was merely exposing sailors to new ideas. But one can still wonder why “How to Be an Antiracist,” a book promoting sectarian racism, is on the reading list as “foundational” material on par with Jim Hornfischer’s classic naval histories. The Navy’s reading list for sailors also includes “The New Jim Crow: Mass Incarceration in the Age of Colorblindness” and “Sexual Minorities and Politics.” Contrary to Gen. Milley and the Navy brass, it is not an assault on open-mindedness to ask whether an institution that requires esprit de corps and a common purpose can function if sailors are primed to view white shipmates as potential “oppressors.”
