I do wish these definitions were still used.
Calling them privilege, focuses attention on the wrong area and away from the real problem. It implies that to improve equity the solution is taking away these "privileges". It also implies some level of moral corruption for those enjoying the "privileges".
It is a race to the bottom where we punish everyone until their experience matches those with the most unjust treatment in society.
Originally it was a word used to describe what I mentioned in the other branch, social privilege, a general set of rules that affect you which enable concentration of means and power. It is not a result of these rules which was the main point of confusion.
It's not an original sin then, the rules can be changed to be more equitable. (Though some changes done under this name are either ineffective or wrong in principle.)
Then someone rightly decided to call whiteness a privilege (a complex of rules pertinent to people declared by society as white, by contrast with the opposite of them), and then somehow it was conflated with immutable characteristics. Yes, a person with light skin color might not actually be or act "white".
Another example: age cannot be changed (at least without), but ageism can. Age is not a privilege, set of rules pertinent to may be. (Some positive, others negative, protective or harmful.)
The opposite of privilege as sum total (which is beneficial rules) is mostly kyriarchy (set of oppressive rules, mostly hierarchies). Perhaps that is a better focus, at least for now.
Given the thread we are in and current strides in gene therapy, we might be there sooner than we expect.
If you don't agree with that concept, you shouldn't cede the linguistic territory by using the term coined by the people who invented that concept
