On the far left, there is often grumbling that we don’t celebrate Martin Luther King, Jr.’s legacy in toto. King was a socialist, and stridently antiwar. This tends to get swept under the rug; if it didn’t, it would be hard to countenance a national holiday. That part of King’s legacy belongs only to the left.

What we celebrate is not what is divisive but what is unifying about King’s legacy: his fight for equality against racism, his dream of a colorblind society — what can be plausibly described as “King’s Conservative Legacy,” but which of course is bigger than that.

We’re not celebrating a man so much as a beautiful idea that he stood for and articulated. And that’s another reason — Steve Sailer, focusing making observance of MLK Day more popular, has floated others — to move this holiday from King’s birthday in January to the anniversary of the “I Have a Dream” Speech in August.
