““the average Wikipedia editor is a well-educated white male.”
And she knows this because she’s sitting behind the shoulder of every editor/poster on Wikipedia as the edit or add new information?
How does Wikipedia prevent non-white non-males from posting material, or editing material posted by others? Does Wikipedia do some sort of racial profiling?
As far as educational level, I guess it's true that educated people have an advantage over uneducated people when it comes to communicating with each other.
Come to think of it, educated people have the advantage over uneducated people in pretty much every area of life.
That is - after all - why we have an educational establishment in the first place. And why we have universities. Which are the main places feminists are paid attention to.
