The fighting in the Gaza strip is an example of how human beings as a race find arbitrary reasons to kill each other. In this case the reason is a set of religious beliefs determined by man himself. Sadly, even if this construct were to not exist, mankind would simply find a new way to divide themselves. Instead it would be far more productive to find ways to unify people with a common positive goal. People would subsequently lead more fulfilling lives and experiance less pain and suffering both on an individual level and as a race.
