In 2017, Angela Nagel published a book called Kill All Normies which helped explain the rise of the alt-right. She focused on two main forums because she felt that they were possibly the most influential and represented very politically different groups. The first of these two forums was Tumblr. I was fascinated by Tumblr culture. And for those who don't know, Tumblr is a micro-blocking website and is very popular with young women - one of the key places where Rowling started to notice these changes online.
