Actually, I have to thank you QS for making me laugh - honestly. It gave me a good hearty belly-laugh.
If I were tasked to self-analyze, I would agree with you - I AM a frightening little man. I'm one of those people, like the college shooter, who can go from 0-60 in 3 seconds; I can play the fool in a group of friends, wearing a lampshade on my head and making balloon animals. The next second, when something goes wrong, I can be putting people in joint locks, scientifically, the way I've been trained, to cause just the right amount of pain to ensure compliance. I know moves to immobilize someone until the police come; I also know dozens of ways to kill someone, quickly and efficiently.
Is that scary? For someone who is not used to experiencing physical conflicts, of course. Is that psychotic? Doesn't that depend upon the reasons I have for doing it?
I'm going crazy for good reasons. I'm only protecting myself and others. Perhaps I scare you for the same reason a guard dog might scare you: he wags his tail and licks your hand one moment and is attacking someone that gets too close the next.
Yet - many people feel better knowing that guard dog is there, on duty, ready to protect you with everything he's got.
Yes, people fear him for his dual nature ... but they're glad he's there. It's human nature to respond to a physical attack with fear and revulsion. I'm just the guard dog that has been trained to react a different way, to get rid of those instinctive responses and react in a focused, purposeful way.
I've had people that threw beer - and beer bottles - at me for helping people. I've been jumped by people. I've also had a lady who gave me her Cadillac for helping her out.
You just never know.
