Emmeline Pankhurst on our banknotes?

You may have heard a couple of weeks ago about the Bank of England's decision to replace Elizabeth Fry on the £5 note with Winston Churchill. As with every item of news, this caused an absolute furore on Twitter. Why was the only woman on our banknotes being replaced by a man? What was the Bank of England thinking, taking such a backwards step for women's rights? Don't get me wrong, I don't entirely disagree with the validity of these questions (although we'll get to my slight qualms about them later). I was, on the other hand, alarmed at the enormous amount of people blithely advocating Emmeline Pankhurst as a better substitute.
