Insulting? Cracker isn't and insult, and it doesn't have the historical baggage the n-word does. The issue isn't the word here. Anyone wight person that takes offense at cracker will be offended at an alternative term, and if we just said white, they'd accuse us of making it about race or whatever, which is doubly hilarious since wight isn't a race.

Policing "cracker" withthis argument is exactly like advocating for the use of the r-slur. The people who'd hear our ideas and would be more open to them if we used neurodivergence slurs is an empty set, so is the people who'd be perceptive but would be taken aback by wights being called cracker. In a nutshell, there's nothing to be gained by dropping it.
