In response to c2W's question about the difference between movies inciting behavior and movies making behavior seem acceptable and/or normal... I think it's one of those things that can seem much more complex and obscure than it is when described with words, because words are especially good at complicating and obscuring stuff. To me, the difference is pretty clear, which doesn't mean I'm right, or that I can communicate my perceptions even if I am. But I'll try.
Social behaviors are learned, and they are learned, IMO, primarily by imitation - even if imitation entails doing what we are told or taught to do rather than what we observe others doing. (I'm not sure what the counter argument is to learning by imitation, unless it's argued that we have an innate and/or genetic sense of behaviors, both moral and practical. If so, a look at cases of feral children might be instructive.) Logically speaking, we don't need to learn how to
feel rage, sorrow, or happiness - those feelings arise in us naturally as a response to our environment. What we do have to learn is the appropriate ways to express those emotions, as well as our desires, and so forth. We express through language, if we understand that language is far more than merely verbal; in fact, since verbal communication is the last thing to develop, we can assume that it is probably the least of it.
Communication has perhaps less to do with what's being expressed than with what's being
received: there are two sides to communication, not just one. So learning to communicate isn't just about finding the most "natural" forms of expression for ourselves, but also learning what's going to be understood by others so as to get the desired result from them. There are two drives behind communication: expressing the self, and
impressing the other.
For a baby, expression of self and impressing the other are inseparable - it's one impulse, one instinct, and both are necessary to its survival. This single function gradually separates into two, opposing desires or "agendas," as the ego identity comes into form, which presumably happens when the infant's expressing of its needs
fails to impress the other, again and again. Getting back to the topic at hand, in a (stereotypical) Jewish family (and at the risk of offending with the glibness of my example), emotions are expressed in a loud, exaggerated fashion, relative that is to a WASP-y environment, where more contained, restrained, and subdued emotional expressions are favored. Take a WASP baby out of its home and insert it into a Jewish family environment and it's going to have to learn more "histrionic" modes of expression simply in order to be heard (and vice versa, of course).
So when disenchanted, disenfranchised, and alienated youths grow up surrounded by images and stories of other disenchanted, disenfranchised, and alienated youths expressing
their disenchantment by doing drugs, having sex at 13, performing satanic rituals, or shooting up their classmates - doesn't it seem likely they would "deduce" (though it wouldn't be a conscious process) that such expressions were an appropriate and necessary form of communication? Like the WASP baby in the Jewish household, their own "natural" forms of expression might begin to seem inadequate for communicating what they are actually feeling, because all the "noise" going on around them is going to drown out any kind of "softer" signal.
Behaviors communicate, and behaviors make up a kind of social language. That what I mean by saying that kids might act in ways that are "against their will." The desire to fit in is one of the most powerful social drives there is, and we all try desperately to find some niche that seems to match and convey our inner state - some way to express who we are in a way that
will impress the other, i.e.,
communicate. If the only glove that fits is one of sociopathic schoolyard shooter, that might be the one we end up wearing rather than
feeling totally alienated.
I'm over-simplifying, but you have to admit there's a persuasive irony to it: choosing the role of outcast is at least
a role, and allows for
some kind of relationship to "the tribe", even if it defines one in opposition to it. Maybe this is how and why killers become celebrity figures, and even cult heroes - an element which is usually included in the "Hollywood" narrative too (Kevin gives a little speech about it in the film) - because they strengthen the solidarity of the group by volunteering themselves as the sacrificial other, or scapegoat? Yet underneath that, they are acting out the deepest, most disowned (unsafe) desires of everyone, which is to reject the safety of the group and forego the need to belong so as to individuate from it, even if by violence.
Another way of putting this is that, since no one is talking to "Kevin" (the autist-outcast), since no one is even trying to learn his language, Kevin is going to talk to "us." To do so, he adopts "our" (society's) language, in the process magnifying and distorting it into a monstrous howl of incomprehension that, at the very least,
makes an impression.
I'm not saying that
movies cause this or that. I'm saying that society's refusal/inability to identify and understand its own monstrous/dis-eased nature, and to open up a real, honest dialogue with its sickly-monstrous children, is perpetuating both the incomprehension and the resulting violence, making it not only necessary but
appropriate as a response - the only remaining way to create a dialogue between self and other.
Intel. programs, mind control, media deception, and irresponsible/uninformed movies are all part of the wall of defense that prevents an honest dialogue from happening. To my mind, they represent the visible, organized vanguard of a collective "conspiracy" to suppress, control, demonize, and disown the dreaded "other" - represented in this case by
the children that we sire - who are now becoming the killers that we create.
There are other arguments above that I'm not sure I can really respond to, because they seem to be predicated on the premise that we are all separate, discreet individuals who are largely responsible for our own decisions, or at least capable of making them and of knowing our reasons for doing so. This is somewhat different from how I perceive things, which is that, as individuals, our actions and decisions are almost entirely determined by unconscious factors, making our conscious 'reasons' merely after-the-fact rationalizations, meant to give ourselves the comfortable illusion of being in control of our actions and decisions.
I'd also say that the "unconscious" that actually rules our lives is a
collective unconscious, which means that we are as, or possibly more, likely to be acting out other people's unconscious drives as our own - there being finally no difference save to the conscious mind anyway. And since the conscious mind only has about 1% of the information needed to judge any given situation, we are like kids trying to put together a jigsaw puzzle when we only only have a dozen pieces, forcing them to fit and saying, "Look ma, it's a rabbit!"
It ain't a rabbit, folks.

It is a lot easier to fool people than show them how they have been fooled.
