In fairness to the actual (not imaginary) offender, he is just an ignorant child whose behavior is no worse than that of many other children three times his age. 

Now that the kid has admitted to the offense, he deserves another chance to straighten up and fly right---if not at this school, perhaps by enlisting in one of the services. (As semi-literate liberal theologians cannot seem to quit saying, " Let he who is innocent cast the first stone.")

I do not tell lies, deface property or write vulgar hateful stuff, yet would be half tempted to pull a stunt like this to provoke reactions by those who are too impulsive and immature for their posts of authority, such as that three-star general.  When people yapping off about "society's" "racism" get exposed for the idiots whom they are behaving like, that gives them reason to govern their emotions and catch up on maturity.
