It amused me to find a thread on mumsnet agonising about how someone's DS (dear son) was reading the BeastQuest books by the tonne (or having them read to him). She was upset that the main character was male & that the main female character didn't do as much. It was therefore, of course, "sexist"!
This is the feminist/progressive mindset: having got him reading at all, she then wanted to control what he read. It's not that there aren't books (Nancy Drew, but really thousands of them) with female lead characters, but that either a) he wasn't reading them, or b) they aren't always as popular; people's choices of reading are what are upsetting her. It must be upsetting for her that the Harry Potter is the main character in the bestsellers. It's the same mindset that had Dr Who disastrously turned into a woman, and will soon do the same for James Bond (which has already contained a rant or 2 against sexism from the new "M" who was at this stage, inevitably, a women). Firstly, they can't produce a franchise with a popular lead character themselves (Lara Croft, Mrs Marple etc are either not successful enough or "problematic in their representation of women") Secondly, they want to control all that we see, hear, say or think. They are, quite simply, mad...and they control the publishers & bookshops, schools, universities and the broadcast media. That's why you should be worried - your liberties are under attack
