The reason why you must choose the company you keep very carefully is because you could be a really genuine person who believes in fairness, justice and equity in addition to natural justice. You may also believe that it is possible for people to communicate and have a reasonable expectation of such values in their lives by commanding reasonable resources.  You never filled out an ethnicity questionnaire in school. It is seldom used in University Applications. The message is that you are just another number to be processed and trained for some form of productivity. Birds of a feather flock together because outside of this school environment, you may find that other people have different hopes of life and society; that they must simply feel and get what they want when they want it in spite of the cost and regardless of who is hurt.  No one bargains for this. It is not "Gangs of New York-the movie" but 911 emergency services and a civil society. Movies depict fiction that might have some historical basis and you could decide if you are living in an era where phones did not exist and there was no universal health care or an airplane. But, there was bacon, dogs, whores, eggs and axes  at best in that historical era.  911 did not exist in the era depicted in Gangs of New York. It depicted a time when the country was, in fact, at war with itself.
So, there is Cain and Abel in every generation or victims and victimizers. You might be an Abel until Cain tries to steal your favorite shoes at gun point. You may become a victimizer when you choose to retaliate. In the process, Cain and Abel become the same person as Abel was converted by a failure to report the crime or tell the principal, taking vengeance into his own hands for a pair of running shoes.  The only way to become himself again is for Abel to confess his sin against his brother Cain. A victim can be a victorious champion if he makes the right choice. Victimizers never win. Their story is obvious to all. A culture predicated on current photo ops, group opinions in the town where you are situated and outward self-esteem based on  group approval is a shifting sand. Standards change as fast as the hottest new pair and currently accepted angle of the frames on the newest ray-bans. As you look behind you to see what the crowd is going to say, have you decided yet whether it was wrong or right to shoot someone for a pair of shoes or because they fumbled the first line in the patriotic anthem(s) that talks about God's grace; after all?  No culture should be a swarthy agent of an eternal hell denying and butting against God's evident grace; all in the fear of a loss of temporary and fleeting social prestige.  Just change your sun glasses and realize that there is another football to be thrown or goal to be scored. Was it worth castrating someone because you felt a little let down?  Memories are just as short as the group's feelings on what Ray-bans are best for social approval. But, they will always agree if good wins. It is the royal law.
