I know it goes both ways. Multiple times, in this same thread, and even in the post you quoted from, I stated that a situation where somebody actually needs peanuts is NOT the same thing. I am not saying that somebody with an allergy "trumps" somebody who needs peanuts. The idea is that if you have other options, since you know peanuts are a item likely to conflict and that among allergens is particularly dangerous, it is just mean to take them to an enclosed area like that if you don't need to. You know. If you are responding, you now know it is a potential issue. So if you can avoid peanuts I just ask that you are a kind person and do so. If you can't, then you can't. That is all. If you can't avoid peanuts then the situation is just an unavoidable conflict. Neither person is necessarily more important, but if it's a preference I hope you can see that potentially risking the life of another may be a little more important than "snack A" over "snack B" for one single snack time. This is a situation in which actual lives can rely on the kindness of others. So please be kind if you can.
Eating peanut butter does not make one a jerk.
Somebody saying "please don't eat that for this one snack right here and right now because you might kill me" and you saying in response "I don't care, I am going to eat it anyways" - THAT is being a jerk.
Can you say with a straight face that it isn't? Until I see it, I don't believe anybody can say that without knowing they are wrong.
Maybe it's just me, I consider other people. If I know that my actions may hurt somebody or cause a problem I try to accommodate them. Even when there is some minor inconvenience. Yes, that means I will avoid other people's allergens even though I have none. Yes, that means I learned to sign the alphabet when I had a deaf customer, started bathing without soap on my son's therapy days for the aid who is sensitive, installed new lights in my salon when ONE person had headaches from the ones we had and I move gathering dates for one sibling who can't come. I have three special needs children with completely different types of needs.
My entire life revolves around changing things for people with some special need. Yes, it can be inconvenient but the entire world does not revolve around one person- which is exactly the point. It is short sighted to turn that argument around to say "the world doesn't revolve around X person" therefore I should do whatever I want whenever and wherever without thinking of anybody. That is completely missing the argument because you are pretending the entire world revolves around you. So think twice before you say the world doesn't revolve around one person, because that includes the world not revolving around you.
Yes- with essentially 100% accuracy, you don't NEED peanuts while you are on the plane. But a fairly significant number of people NEED you to NOT have peanuts on that plane. So grow up and just take a minute to think of somebody who isn't you. Especially if you are being accommodated in some way. Avoiding peanuts for one snack is not a huge inconvenience, it is just childish to pretend it is.
