Early Sunday morning, I posted a “strongly worded” (Rich Lowry’s description) condemnation of the conduct, seen far and wide on video, of a group of high-school students at the conclusion of the March for Life on Friday afternoon. I was preachy and rhetorically excessive, and I regret it. The overheated post I wrote has been taken down. Let this apology stand in its stead, both here on the Corner and in the memory of readers who justifiably objected to my high-handedness.
