Labelling the “science” as “dubious” is basically slighting the people attempting to track these slights at something other than a personal level.
Just because the stories you hear don’t jive with your take on the zeitgeist doesn’t mean the stories are wrong. It could just be that you aren’t the type of person that gets slighted often simply for existing the way you are.
On one hand there’s valid criticism of collection techniques, on the other there’s dismissing the entire proposition that slighting is a thing that happens because you don’t like the way the collection is done.
A better critique would look at ways to improve data collection, but that requires quantifying the myriad ways we slight each other. How to write that all down?
