I am not a Polack. People from Poland are Poles, not Polacks. But what I am is a one hundred percent American, born and raised in the greatest country on earth and proud as hell of it, so don’t ever call me a Polack.
– Tennessee Williams
A Streetcar Named Desire, Scene 8. Stanley snaps angrily at Blanche after she makes derogatory remarks about his ethnicity, calling him a "Polack, without a nerve in your body." He responds to her insult implying she is superior to him and he is lower in the class system, by proudly declaring that he is a born and bred American.
