FWIW in the "Oxford Dictionary of English" that's built into iOS, if I look up "fairness" I get
> 1. impartial and just treatment or behaviour without favouritism or discrimination.
> [...]
(the other definitions refer to pale skin or beauty)
It sounds like your definition is more of a list of synonyms — I was using the current Oxford dictionary available on iOS and Google.
> I'm not an expert on "radical socialist, communist, CRT-type Instagram accounts", but I'd have thought they would be more into equality rather than fairness, e.g. everyone gets the same pay irrespective of how much effort they put in or the quality of results.
Yes, exactly that, and that's what your comment above was doing, no? You reframed fairness as meaning equality of outcome, and framed equality as meaning equality of opportunity. (Equality of outcome = same end-height, equality of opportunity = same ladder height)
