This is getting very nasty and i think it is highly out of place!
From one diabetic to another, ther are plenty of snacks that are high in protien, besides nuts!
When i have had to fly i always bring Choice bars with me as they are high in soy protien, and meet my diatary needs. Is this really a case of you being put at risk or are you just mad cause you couldn't eat your peanuts?
How would you feel if someone on the plane 5 rows back got very ill and died beacause the peanut particles from YOUR snack got on their skin? Some people are so allergic that even skin contact could do them serious harm, and unless you live in a bubble, any peanuts in the air can kill!
This is why airlines schools, and even some restaurants have eliminated nuts from their menus.
Sure, i like nuts as much as the next person, but its a small price to pay to keep someone from getting ill.
