It's not casual, it's factual. If peanuts are treated this way, it sets a precedent for other kinds of allergies too. Or are you suggesting that somehow peanut allergies get special treatment?
If we treat them all the same, it can spiral very quickly.
First it's the peanut allergy parents.
Then sends, or tree nuts.
Then maybe the egg ones.
Then dairy.
And strawberries...
In a good sized primary school, there can easily be children with serious allergies to any of these things.
So the answer is, according to you, to ban all of these foods?
It's not just the fact that this will be seriously restrictive of all the other children's diets - it's not just avoiding one product like peanut butter. Or that some of these kids may have their own significant issues which make such a restrictive diet a problem.
You are arguing for this despite the fact that the research doesn't support it.
Despite the fact that allergy groups don't support it. Nor do specialist doctors.
I'm not sure how I, or anyone else, is bad for wanting an approach that is both evidence based and fair. It seems to be because you think you can just use emotive language and that is what determines the best course of action.
