Ah, this lovely new trend among academic types of describing an individual as a "body". For a group of people said to be so interested in the human condition, it's a strikingly dehumanizing term.

The article describes the term as catching on among the activist left in general, but this particular usage finds its origin in academic papers from the humanities.
Probably even the word "anybody" comes from this usage. It's old and widespread.
I assume the terminology is intended to deliberately draw one's attention to this.
