“I think "immoral" is probably the wrong word to use…I prefer the word "unethical."”

… What excellent advice it is, and how it was beaten into my generation of schoolboys... But one may tire of even the best advice, as one may tire of writing according to these precepts. Would we wish to be without the heraldic splendour and torchlight processions that are the sentences of Sir Thomas Browne? Would we wish to sacrifice the orotund, Latinate pronouncements of Samuel Johnson? Would we wish that Dickens had written in the style recommended by the brothers Fowler, who framed the rules I have quoted; what would then have happened to Seth Pecksniff, Wilkins Micawber, and Sairey Gamp, I ask you?

Answering a suggestion that the Soviets would prefer a Conservative government led by Margaret Thatcher than a Labour government headed by Neil Kinnock at a press conference in Moscow after a meeting with Anatoly Dobrynin (11 May 1987), quoted in E.

Certainly we all want to live the well adjusted life in order to avoid neurotic and schizophrenic personalities. But I must honestly say to you tonight my friends that there are some things in our world, there are some things in our nation to which I'm proud to be maladjusted, to which I call upon all men of goodwill to be maladjusted until the good society is realized. I must honestly say to you that I never intend to adjust myself to segregation and discrimination. I never intend to become adjusted to religious bigotry. I never intend to adjust myself to economic conditions that will take necessities from the many to give luxuries to the few. I never intend to adjust myself to the madness of militarism and the self defeating effects of physical violence.

The Humanist interview (2012)
Context: I think most social justice movements take the words that are used against them and make them good words. That’s partly how “black” came back into usage. Before we said “colored person,” or “Negro.” Then came “Black Power,” “Black Pride,” and “Black Is Beautiful” to make it a good word.
"Witch" was another word I remember reclaiming in the 1970s. There was a group called Women’s International Terrorist Conspiracy from Hell (WITCH). They all went down to Wall Street and hexed it. And Wall Street fell five points the next day; it was quite amazing! “Queer” and “gay” are other examples. … I think we all have the power to name ourselves. I try to call people what it is they wish to be called. But we can take the sting out of epithets and bad words by using them. Actually, I had done that earlier with “slut” because when I went back to Toledo, Ohio, which is where I was in high school and junior high school, I was on a radio show with a bunch of women. A man called up and called me “a slut from East Toledo,” which is doubly insulting because East Toledo is the wrong side of town. I thought, when I’d lived here I would have been devastated by this. But by this time I thought, you know, that’s a pretty good thing to be. I’m putting it on my tombstone: "Here lies the slut from East Toledo."
