Springhole.net, one of the remaining early internet sites with a mary sue litmus test, has gone regressive and put up a note in the mary sue test page demanding people stop using the term by falsely claiming that the term is "just used to tear down female characters simply for having a prominent, active role in a story.".

Hardly. No one calls out Ellen Ripley or Lara Croft (Angelina) as Mary Sues, people use the term as per its meaning... what changed in holywood was that they cant be seen to show women fail (thanks feminism) and now we have an abundance of them.
