Final answer:
The Onslaught movie clip likely depicts the prevalence of violence in media targeted at young people, illustrating how such content is not only common but also often presented in an acceptable light, potentially influencing viewers in a cyclical and complex manner.
Step-by-step explanation:
The point of the Onslaught movie clip with the young girl in the online lesson is likely to emphasize the widespread presence and potential impact of violence in media that is geared towards children and adolescents. When considering the context provided - a student-produced documentary about the effects of television on society - this clip seems intended to showcase how violence is not only present but often condoned and acted out in popular media consumed by the youth.
Furthermore, the strategic placement of the clip could be an illustration of how such media influences can be cyclic and endless, similar to the concepts described in point 11 from the reference, which discusses the unending combinations and circular nature of the direct and indirect leads in military strategy. The clip could also imply that just like in a strategy, there can be simulated disorder in media representations of violence, which may have an underlying structure or intention that isn't immediately obvious to the viewer.
