School and Allergies

Alright, I don't know how many of you had heard about the incident in Florida where parents of a child with food allergies was asked to home school (I don't believe the school itself did this because it's illegal, but I could be wrong). Many people are throwing out opinions like "Parents should be teaching their children to be kind to those with allergies. It's not that hard to follow an allergy list."
Here's my opinion. It is that hard. Not so much at home (this depends on the amount of allergies the child has) but in a school setting where there are 20 or more students per room, how many do you think have allergies and to how many things and to what degrees?
For me, at home, having a child with mild allergies to dairy, eggs, peanuts, and ham (this includes baked goods) is not that hard. Even if he has something he's allergic to, it just means we're going to have to deal with diarrhea. The doctors even told us he may grow out of it, so in a few years when my son is attending school, I will test him again. Of course, I'll tell the teachers to avoid it so they don't have to deal with his messes, but if he ends up getting some, it won't be the end of the world.
For others, that is harder. There are some who will quite literally die if there was contact between their allergy and a spoon used to stir the dish. Obviously, they'll have to be a lot more careful about where the food came from, who made it, how careful were they, etc.
Honestly, I don't understand why food served in a school should be any harder to figure out than food served at McD's. Now mind you, it was mind blowing when I was reading the allergen list at one of our favorite drive-thrus (they have milk in their french fries) and it is a lot to take in until you start crossing off things my child wouldn't eat anyway...
They should have a simple sticker system showing what allergens (at least the basic 8) are in the foods they serve so that the child with allergies can learn to spot them himself. My son knows if I pull down the jar of peanut butter, he's getting the almond butter. If I pull out a gallon of milk, he's getting any number of non-dairy milks. He does get some of his allergens (again, not life threatening) but that is my choice as a parent.
To other parents (those with children without allergens), it's really not that hard to find allergy free stuff. In fact, Starbucks (number 1 coffee shop) sells allergen-free cookies right on it's counter top (you'd have to buy them one at a time) and if you're looking for dairy-free, egg-free, peanut-free cookies then Oreos (yup) is awesome.
