Following the posting of this 'proof' on another forum, I did an analysis.

Introduction
The first issue I come across in the introduction is the claim that JK's essay is purposefully too long to obscure the facts and true intent. The essay takes around 9 minutes for a slow reader I would estimate, and is a concise, whilst personal communication of the main problems JK has with the erosion of women. It's hardly surprising, as the other side relies on snappy slogans that don't stand up to much deconstruction, #twawnodebate.
^JKR’s original post was long and it contained so many falsehoods it is very tricky to address concisely, therefore this article is very long.^
Now, this statement I would argue is false, yet implies the writer has done the leg work so you don't have to read the original essay. However, I would estimate it to be around the same length as J K Rowling's essay so the save you time argument falls flat. It does, however give it's own reading of the text which happily I have spent some time looking into so here goes. (Literature nuts please feel welcome to deconstruct as we go. It's no Heart of Darkness, but it is an interesting analysis exercise.
