Why the need to deny bias that others have experienced?

No, but Kite is a commonly used word and toy. Niggardly isn’t known or used in any casual/formal speech. The only instances anyone has heard/used it, is in discussions of English literature or in reference to it’s similarity to Nigger.

So when I hear it outside of these contexts I assume someone is race-baiting. Not the same as Kite. Not even close.
