Call it the not-so-soft bigotry of low expectations, WD.
By not expecting - no, DEMANDING - that people act with a modicum of humanity (let alone some emm-effing CLASS), we foretell the self-fulfilling prophecy that they will devolve into lowest-common-denominator behavior.
They should be insulted by the hand-wringing expectation that they'd behave this way. THIS is the attitude that really fosters class differences...the "Oh, well. THOSE people don't know any better" attitude.
People who engage in sub-human behavior need to be TREATED like they are not human. Vicious animals - those that attack humans - are typically destroyed. Put that policy into effect - summarily waste a couple of thugs in a very loud, dramatic, and grotesque manner...betcha the herd will fall into line.
