I'd have to agree with the poster who mentioned how people in communities are slow adopters of change. If you moved into an apartment in the city and yelled at the kids who live in the building with you to get off the stoop or stop doing things they were doing long before you arrived - you'd meet resistance there as well. There's conflict in many areas these days where people have bought up cheap land and thrown up big houses or developments in areas where the people around them have lived for generations. Feathers have been ruffled so things are getting said and things are getting smashed. If they weren't black, they'd be calling them fat, old or yankees by way of insult. People with small vocabularies and limited imaginations really can't do much better than calling out the most obvious of epithets.
