Exactly!
Yep, exactly.
And, I am a parent of a child with a life-threatening peanut allergy.
However, it is good to have some safe guards in place to prevent accidental exposure, especially for elementary age kids. My wife and our child's school have worked well together in establishing sensible safeguards.
When my kid was 9, at home, he ate a couple bites of a washed apple that had been handled by someone who had eaten peanut butter and within a few minutes he wasn't moving air. Thankfully, epinephrine worked fast and well.
His reaction, as scary as it was, was a many-fold blessing: One, he was with us and we knew what was happening when he said that his "throat felt like it was squeezing"; Two, ever since it happened, he/we is/are much more careful and responsible when it comes to the whole issue.
Prior to this allergic reaction, his doctor (Johns Hopkins) told us that his allergy "was off the charts" and that he could die within 10-15 minutes of ingestion of a peanut/peanut product, which caused us alarm, but it became very very alarming after his first reaction.
His doctor also said that repeated exposure potentially leads to stronger allergic reactions, which may be irreversible, even with an epinephrine injection.
I don't agree with the approach in the article, but I do believe that if someone's child faced this level of significant danger on a daily basis, at their local elementary school, then that someone would be much less cavalier about the subject and how it was handled.
