The article writer is an idiot and you may be too. It says nothing about DEI expertise.
This is equivalent to dunking on scientists when a flat earther claims to be a “science expert”.
The screenshot here in this very thread specifically says that they are an expert
I can call myself a Professional Moron Noticer and point to you but that doesn’t make it true or fair.
If you were to buck the odds and say something intelligent in response it would even attack my “expertise” publicly, like a “DEI Expert” saying some racist nonsense in a published article.
