All these disgusting people were always there. Spreading their misogyny left right and bloody centre.
Social media gives these people peer-to-peer bunk ups. They're all gathered together. Similar to incels. Goading each other on, praising each other's repellent views.
Normal people don't think this way.
Most people aren't on Twitter.
J. K. Rowling is in touch with normal people, whose children are sending pictures to her and to whom she is replying.
The parents of these kids couldn't give a flying fuck about what some sexist twit on the Internet says.
