SELIGMAN: You shouldn’t use this word. 
It’s not what you call “politically correct”… 
’Negro’
…
JOE: Well, excuse me, but
 in my circles,
 it’s always been a mark of 
honor to call a spade “a spade”. 
Each time a word becomes prohibited,
 you remove a stone’s
 from the democratic foundation. Society demonstrates its impotence 
in the face of a concrete problem, by 
removing words through the language.
SELIGMAN: I think society would claim that the political correctness is
 a very precise expression
 of democratic concern for minorities.
JOE: 
And I say that society is so cowardly
 as the people in it, who are, in my opinion, 
too stupid for democracy.
SELIGMAN: I understand your point, but I totally disagree. 
I have no doubt in
 the human qualities.
JOE: The human qualities can
 be expressed in one word: hypocrisy. 
We elevate those who say “right”, 
but mean “wrong”, 
and mock those who say “wrong”, 
but mean “right”.
