The Post should join this campaign for sanitized names, thus purging the present of disquieting references to the past. The newspaper bears the name of the nation’s capital, which is named for a slave owner who also was — trigger warning — a tobacco farmer. Washington, D.C., needs a new name. Perhaps Eleanor Roosevelt, D.C. She had nothing to do with her husband’s World War II internment of 117,000 persons of Japanese descent, two-thirds of whom were native-born American citizens…

To Massachusetts and Minnesota, which should furl their flags. Massachusetts’ flag shows a Native American holding a bow and arrow, a weapon that reinforces a hurtful stereotype of Native Americans as less than perfectly peaceful. A gimlet-eyed professor in Wisconsin has noticed that Minnesota’s flag includes the state seal, which depicts two figures, a pioneer tilling a field, and a Native American riding away — and carrying a spear. A weapon. Yikes. The farmer is white and industrious; the Native America is nomadic. So, Minnesota’s seal communicates a subliminal slander, a coded message of white superiority. Who knew that Minnesotans, who have voted Democratic in 10 consecutive presidential elections since 1972, are so insensitive?

This is liberalism’s dilemma: There are so many things to be offended by, and so little time to agonize about each.
