“If I were on that plane I would have smacked the shit out of that teenager.”
I would have defended the teenager, and lots of others. People with “peanut allergies” are crazy, and so are those who “smack” people .
Two year old children are not crazy because they go into Anaphylactic Shock in the presence of allergens.
As well, if a person with a bomb came to sit in proximity of you and your family, or your Neighbor's, it would be yourself who is the crazy one for not effectively dealing with the problem.
