Well, that article was a revelation. I particularly enjoyed the tribute to Jeremy Paxman as the champion of diversity. University Challenge is often criticised for perpetuating privileged perceptions of knowledge. I have always found Paxman rather condescending to people who haven't had his Oxbridge education and suspect that he is sometimes less acerbic towards attractive young female contestants.
Amol Rajan took precisely the line that a good journalist should take by condemning the abuse JKR has received on the grounds that the abuse is unacceptable, whatever one's personal views on single sex spaces and transgender politics. If nothing else, the stabbing of Salman Rushdie is an awful reminder of the need for free speech in a democratic society.
I don't know about Samira Ahmed's views. She's a good presenter and journalist but tends to take a neutral line on the topics she's discussing. I did admire her taking the BbC to tribunal over differences between women and men's pay.
