The stereotype that skate boarders are dangerous was used by the cop who accused the skaters unjustly. Stereotypes are used because people choose to be ignorant. Stereotypes will just be passed on as the gossip rolls. You can t defeat a stereotype. So the next time someone uses stereotypes like blonde bimbo, dumb Polock, bad skate boarder, lazy teenager, macho Italian, rich snob, tough jock, bushwhacking African, surfer dude, prejudiced bald kid or the dirty pig stop and inform them that pigs are actually very clean animals, and people are not dumb because they are Polish.
People are dumb because they use stereotypes.
