Why more violence in hockey?

For those who've wondered why it is that hockey players are involved in more scuffles during games than athletes in other sports, and why games often erupt into violence, I have a theory: frustration.

Frustration: an act of hindering someone's plans or efforts; a feeling of annoyance at being hindered or criticized; the feeling that accompanies an experience of being thwarted in attaining your goals.

We all know that feeling; what it's like to be frustrated in something we try to accomplish.
The anxiety of an unmet goal can be very oppressive, even defeating.

The main source of frustration in hockey is the difficulty of handling the puck with your stick. The constant inevitability of losing control of the puck, combined with the fast pace of the game and the near chaos of the arrangement of players on the ice, creates an environment of frustration. Unlike in basketball, football, and baseball (even soccer affords more control over the ball), hockey players are continually thwarted in simply getting from point-A to point-B (a short distance in a short amount of time, too) with the very object of their game, using the main modes of conveyance in their sport, stick-handling and passing.

As a basketball player, if I constantly had the ball stolen from me while I was playing, I would get very frustrated!
This frustration, I believe, is the single greatest source of the edginess, short tempers, and uncontrolled aggression that is so characteristic of hockey and many of it's players.

Which brings us to the subject of violently fanatical Muslims, and their frustrations...
