Victor Davis Hanson‘s latest column at National Review Online offers words of warning to the ideological left.

The latest round of condemning the past on the moral criteria of the present started with banning the Confederate flag from public places. Now it is on to airbrushing away progressive old white guy Woodrow Wilson, in Trotskyized fashion, from public commemoration.

But do those on the Left realize that they are rapidly becoming captives to the consequences of their own ideology? Their current effort to rewrite the past is doomed to failure for a variety of reasons.

First, this damnation of memory is not a balanced enterprise, but predicated on today’s notions of politics, race, and gender. No one is insisting that the great work of Martin Luther King Jr. be dismissed from the pantheon of American heroism because he was a known plagiarist and often a callous womanizer who did not live up to our current notions of gender equality. The racist eugenicist Margaret Sanger is still a saint.

No one is claiming that Franklin Roosevelt was a third-rate president because his State Department was full of racists and anti-Semites, who were not too bothered by reports reaching the United States about the Final Solution, and who green-lighted the illegal internment of Japanese-Americans.

And why is Mohandas K. Gandhi exempt from left-wing ethical erasure? Was not his creed of non-violence tainted by the fact that his opposition to apartheid did not include much sympathy for blacks, while his advice to Jews facing extermination in Europe was heartless and anti-Semitic?

To be fair, shouldn’t liberals demand that the memory of César Chávez be airbrushed? In 1969 Chavez sent his union thugs to the border to help turn away illegal immigrants, and he called for closing the border to prevent future illegal immigration. The finances of his United Farm Workers were conducted like a tribally run mafia enterprise. By present standards, Chávez’s behavior might be called xenophobic, vigilante-like, and nativist.
