YESTERDAY CAME SUDDENLY: All your childhood memories are probably racist.

Did you know that Paul McCartney once wrote a song celebrating slavery? Well, neither did he. It took about half a century after “Penny Lane” was a hit for the Beatles before historians decided that this street in Liverpool was a legacy of the trans-Atlantic slave trade. Sir Paul wrote the song as a nostalgic ode to Penny Lane as the scene of childhood happiness “beneath the blue suburban skies.” The Liverpool-born musician could not have known, while composing the cheerful tune in the mid-1960s, that scholars would one day conclude Penny Lane was probably named in honor of James Penny, a local mariner who made his fortune in the slave trade in the 1700s. Historians have not been able to prove this as a certainty, but the mere possibility was enough to inspire vandals to deface a sign in Liverpool with graffiti: “RACIST Lane.”

History is a horror show for liberals, who only look to the past in search of grievances they can exploit in their remorseless quest for political power. The liberal has a quasi-religious faith in Progress, which means that yesterday — another McCartney song title — was self-evidently worse than today. The past was a bad time, according to liberals, who see nothing there but oppression. Your nostalgia for the pleasant memories of childhood is almost certainly racist, and probably also sexist and homophobic. Now that I think about it, didn’t McCartney’s lyrics in “Get Back” mock someone who “thought she was a woman, but she was another man”? Isn’t this the textbook definition of transphobic hate speech?

Even the Beatles may not be immune from The Great Forgetting:

As the Who suit up for what I suppose will be their final tour (“Who’s Left”?), Chuck Klosterman points out in his book But What if We’re Wrong? that whole forms die out. He compares rock to 19th-century marching music: nothing left of the latter except John Philip Sousa. That’s it. And Sousa himself is barely remembered. In 100 years rock might be gone too, Klosterman guesses. Maybe we’ll remember one rock act. Who will it be? Maybe none of the obvious answers. It certainly wasn’t obvious at the time of Fitzgerald’s death that The Great Gatsby would be the best-remembered novel he or anyone else wrote in the first half of the 20th century. As for the novels of the second half of the 20th century, the clock is ticking on them. The Catcher in the Rye is moribund. Generation X was the last to revere that book. Teaching it to young people today would get you ridiculed. To Kill a Mockingbird? It had a good run but it’s now being labeled a “white savior” story by the grandchildren of those who revered it. Soon schools and teachers will be shunning it.

To Kill a Mockingbird? Atticus Finch is literature’s most celebrated rape apologist!
