If we used the "logic" of the pro-abortion/euthanasia/eugenics crowd, i.e., the Democrats, we would mandate those individuals eat peanuts to eliminate their bad genes from the gene pool as fast as possible.
I guess it isn't important unless you're the parent of a child who has the allergy---and that would change your opinion PDQ.
My cousin had a child with the allergy --first time I ever heard of it--and it was horrible--because peanuts are in many things that kids eat. And it is life-threatening at times.
I have friends who have a new two-month-old who has been diagnosed with a metabolism disorder that will require medication and diet all her life. I told the parents that it could be worse--she could be allergic to peanuts. They agreed.
