I see what you’re saying, but I don’t think one must “feel threatened” in order to be in danger. I have never understood that concept the I “feel safe” in Oakland/Compton/Brooklyn, etc mentality. I am a little too objective for that. There are many potential risk factors in any situation, and I tend to look at every situation from that perspective.
I don’t necessarily feel at risk on an airplane, but I understand the risks that exist when boarding a plan with 100 strangers.
