Not that I'm one to side with the MSM very often, but I do have to point out this isn't a newspaper article. It's just a "press release" by someone who really doesn't know what they're doing. You can tell from the false headline that this isn't any real news story. (The guy wasn't arrested for objecting to a homosexual curriculum; he was arrested for refusing to leave the premises after any meaningful discussion had ended.)
You are, of course, correct about appositives. From the AP Stylebook:
PUNCTUATION: Do not set an essential phrase off from the rest of a sentence by commas:(I'm more into annegatives, myself.)We saw the award-winning movie "One Flew Over the Cuckoo’s Nest." (No comma, because many movies have won awards, and without the name of the movie the reader would not know which movie was meant.)
They ate dinner with their daughter Julie. (Because they have more than one daughter, the inclusion of Julie’s name is critical if the reader is to know which daughter is meant.)
Set off nonessential phrases by commas:
We saw the 1975 winner in the Academy Award competition for best picture, "One Flew Over the Cuckoo’s Nest." (Only one movie won the award. The name is informative, but even without the name no other movie could be meant.)
They ate dinner with their daughter Julie and her husband, David.(Julie has only one husband [at least that's what David thinks]. If the phrase read and her husband David, it would suggest that she had more than one husband.)
The company chairman, Henry Ford II, spoke. (In the context, only one person could be meant.)
Indian corn, or maize, was harvested. (Maize provides the reader with the name of the corn, but its absence would not change the meaning of the sentence.)
DESCRIPTIVE WORDS: Do not confuse punctuation rules for nonessential clauses with the correct punctuation when a nonessential word is used as a descriptive adjective. The distinguishing clue often is the lack of an article or pronoun:
Right: Julie and husband Jeff went shopping. Julie and her husband, Jeff, went shopping.
Right: Company Chairman Henry Ford II made the announcement. The company chairman, Henry Ford II, made the announcement.
Well, sort of. He called in to Howie Carr. He said he was told he'd have to go through "proper channels" (whatver that may mean) and it would take some time. He asked about some kind of help in the meantime until it was finalized. The principal -- and vice principal? -- put a call in to the superintendent of schools. They were still on the phone with him when the police arrived.
