We live in an age of unbridled white id.

Many days it is anything goes, baby, from the White House to the baseball stands; objecting often draws a scornful wave of the hand and a lecture on political correctness.

The latest eruption comes courtesy of Josh Hader, a 24-year-old white relief pitcher with a smoking fastball and a Twitter account filled with hideous thoughts typed when he was 17 and 18. A Hader sampler: “White Power, lol” (with an emoji of a clenched fist), “KKK,” and “I hate gay people.” He also used that vilest of words for black people.

This all came to light as Hader pitched in the All-Star Game last week. After the game, he mumbled something about being influenced by rap lyrics. Then he abandoned that tack and began apologizing profusely. “I was 17 years old, and as a child I was immature,” he said, “and obviously I said some things that were inexcusable.”

Point of information: A 17-year-old can drive or serve in the military, and is a year away from voting. That does not describe a child. I’m not unforgiving of youthful stupidity, although it would have been swell if reporters had asked obvious questions: How was it that you attended an integrated high school in exurban Maryland and yet posted racist and homophobic comments? From what sewer line did those sentiments bubble up?
