I don't think he's over reacting. The majority of the school children have to change their diet or be relegateed to a cast-off type table over the allergy of 1 kid? That's unfair. I think it's great someone finally stands up to the dumb-ass "administration."
I understand fully the severity of peanut allergies. A kid in one of my daughters class has a peanut allergy. My daughter chose to be in the class and go peanut-free. OK, her choice, but I will not stand for any of my kids being forced into the measures necessary to accomodate %0.0125 of the school population. It's just unfair.
I guess we just agree to disagree, then. I think calling a minor inconvenience "suffering" is silly, and encourages an environment where everyone maximizes their complaints instead of ignoring things that are not, actually, painful or incapacitating.
He's not going to ZOT the school into common sense, so what's gained by encouraging his girlfriend's daughter to cry, "But I'm a victim, TOOO!"?
