Which brings us back to the original question. What brings one to such a point where they feel their safety is so compromised they must bring a gun onto a child's ride at Disney World? What were the life choices this man made that led him to this sorry state?
I don't think it's an issue of feeling particularly unsafe at any time. This person obviously conceal carries all the time, everywhere, even where prohibited. Why would he give Disney Land a free pass, or change his behavior?
Trying to conflate taking a gun on a child's ride with a particular trauma that would render him unable to ride it without a gun is silly.
Further, he doesn't have to feel unsafe in particular to conceal carry anyway. "safety" is a continuum - there are few times when any human feels
perfectly safe, except,perhaps, as a child. Most people feel safe enough most of the time, and they avoid situations where they don't feel safe. Some people increase their self-sufficiency in terms of safety by taking classes to improve their self defense, moving to locations they believe are safer, or changing their routines and behavior (such as traveling with friends).
Having a gun is merely an extension of that.
While a gun is arguably more deadly, particularly at a distance, would you be worried if someone took their concealed black belt martial arts ability on a disney world ride?
Would you be thinking, "What brings one to such a point where they feel their safety is so compromised they must bring their martial art onto a child's ride at Disney World?" What if they carried a 3" steel rod on their keychain as well, multiplying their already deadly ability? Would you feel particularly unsafe if you were riding on the same ride as a dozen members of a martial arts club?
