Our original article pre-apology:
Really American Idol, really?
On the March 19, 2014 episode, the TV show’s host Ryan Seacrest told Caleb Johnson, a Top 10 Idol finalist, that a viewer wanted to know how he managed the stress of the competition.
Johnson, a 22-year-old rock singer from North Carolina, thought he was amusing when he gave an answer about cutting tension with pranks among the contestants. He started with an example of smearing shaving cream on noses. Then he went on: “Superglue on the toilet seats; Alex [Preston] is peanut-allergic, so putting peanuts in his socks and underwear.”
As a fellow contestant belted out a shocked laugh to the peanut suggestion, Johnson quickly said: “That’s a joke.” (It hadn’t, in fact, happened.)
But this is no joke, and there is no peanut allergy “pranking”. Peanut allergies can lead to severe, even life-threatening reactions, and studies have shown about 30 percent of students  with food allergies have been harassed or bullied because of those allergies.
Seacrest, at least, seemed to get the inappropriateness of Johnson’s comment in regard to Preston. Immediately, he chimed in: “That’s like torture.”
Yes, Ryan, that kind of “pranking” is bullying – nothing funny in the least about it. It’s unfortunate American Idol, which is watched by millions, didn’t find a way to edit the comment out of the program. The takeaway that this is somehow amusing is disturbing.
If I were Alex Preston, I’d take a wide berth of this fellow contestant; the one who needs to get himself some sensitivity – and a filter.
