When he was an N.F.L. punter with the Minnesota Vikings, Chris Kluwe was known for speaking out. He hasn’t stopped in retirement.

Mr. Kluwe was arrested in Huntington Beach, Calif., on Tuesday night and charged with disrupting a City Council meeting.

He was objecting to plans for a plaque celebrating the 50th anniversary of the Huntington Beach Central Library, which included the words “Magical,” “Alluring,” “Galvanizing” and “Adventurous” — the first letters of which spell “MAGA,” President Trump’s slogan meaning “Make America Great Again.”

The proposed plaque continued with a more explicit reference: “Through hope and change our nation has built back better to the golden era of Making America Great Again!” — also alluding to the “hope and change” and “build back better” slogans popularized by former Presidents Barack Obama and Joseph R. Biden Jr.

Mr. Kluwe, who said he had lived in Huntington Beach for 15 years, was one of several citizens who rose to speak at the public hearing. “Everyone is in favor of a plaque to celebrate the library, but the vast, vast majority are against including a MAGA acrostic,” he said, standing at a lectern with a microphone. “Unfortunately, it’s clear that this council does not listen.”

“MAGA is explicitly a Nazi movement,” he said, drawing applause. “You may have replaced a swastika with a red hat, but that is what it is.”
