Oscar Hammerstein introduces the song "You've Got to be Taught" during B...

Nobody admits to being prejudiced anymore, but there is still a lot of it going around. People today can always give you a reason why they are ill-disposed to a certain group. Bad hygiene, too noisy, criminal minded, unacceptable political policies, just want free stuff, lazy, drug-addled, hate America, ungodly, bad smelling, overemotional, acquisitive, selfish, it could be anything, but they'll have a reason. Like that makes it okay! 

The reason more likely is the one given in this nice song. They were taught.
