A large portion of people use "nuance" as a self-serving euphemism for their own lies or corruption, and explicitly call for no nuance when demanding conformity.
"Nuance" is an elite get out of jail free card: You're just too dense to understand how I was fundamentally right about everything when I was wrong in exactly the way you said I was wrong. The fact that I agree with you now is because there's finally enough evidence. Actually, it's a sign of your stupidity that you were "right" before. You should actually be grateful that I've come to agree with you; it shows how flexible and open to new information I am, and how lucky you were.
