Ill try and explain a few of the things that happen here using my own experience .
First, we need to define the universal human phobia. It is not snakes or sharks or the dark or any of that stuff. It is interpersonal human aggression. It seems that animal species are very often hardwired to not attack their own kind. Nowhere is this more evident than in human beings. Despite the violence we see on the news and so forth, the vast majority of us do our best to maintain the social contract and not harm each other. Even people engaged in wars have historically made almost ludicrous attempts to avoid killing the enemy. Of course, there are a small percentage of people that do not exhibit this trait and will use violence at the drop of a hat.
The fact that nobody in the group even appears to react(prof. x mentions how no one even shouts at the guy to stop) is quite common when humans are confronted with the universal human phobia. A phobia reaction can take a number of forms, but for some reason, a common reaction to the UHP is to deny it is happening. That effect is made worse by the fact that most people realize that violence like that is directed specifically against one target and if you completely stay out of the conflict, you have almost no chance of being hurt.
Like it or not, self-preservation is the most powerful drive we have in almost all cases.
Be honest. How many of you guys at least experienced a somewhat elevated heart rate watching this? Do the mental exercise of putting yourself in that pizza parlor and see what you experience.
Now, the question becomes what can you do about it, because the beating of this guy in a roomful of men capable of defending him is inexcusable.
I have a couple of answers but none of them are easy.
The first is a mental exercise. Military and law enforcement officers (at least the good, capable ones) go through a regular practice of visualization. I do it every shift in my patrol car. Mentally put yourself in a situation like this pizza brawl and resolve yourself to act. The effect is even more powerful if you use actual circumstances around you to enhance the experience (ie…if you are on line at walmart, run a briefly run walmart scenario in your head, maybe even picking out a guy that looks tough as your “bad guy”.) Believe it or not, this steady visualization game vastly improves performance in violent situations for a host of reasons. Just make sure you see yourself acting appropriately and decisively.
Next, take responsibility for your own survival. If you are able, carry a firearm and train in its use. You, your family’s or maybe some helpless other person may rely on you some day. Dont go anywhere without this firearm. If I step out of the house to go to a store for the damn newspaper, I have a gun on me. (BTW, it is a topic for another day about if and then how a firearm should have been employed in this particular case.)
If you cant carry a gun legally, or absolutely refuse to (which is a shame, really), then physically prepare yourself for violence. Everybody here is probably in excellent physical condition, so that is not an issue. Im talking about real fighting skills…muay thai, boxing, wrestling etc. Not only will these improve your odds of surviving a violent confrontation, it will improve the odds that you would enter such a fray to begin with. To wit, if 6’8" UFC fighter Tim Sylvia was on line behind the guy that got beat up, he would have been much more likely to intervene than some milktoast accountant with a size 12 shirt. This is common sense. Sylvia knows he could knock that belligerent piece of shit the fuck out because he has done it before. There is only so much you can do to improve your physical
capabliities, but if this kind of thing really pisses you off, then you have an obligation to do so.
Lastly, make peace with yourself that you will not ever let something like this happen in front of you. Lets be fair and say that human nature and societal conditioning were working hard against those bystanders in the pizza place. But lets also say that good men dont want that for their society, and we need to resolve beforehand to draw our line.
The shitty thing about experience is you never have enough until you need it. Unless you want to go live in an urban war zone and play superhero(and live a much shorter life in the process), your exposure to this kind of thing will be very minimal.
PLease heed some of my advice. It could be anyone of us catching the beating one day.
Stay safe
