"Exactly like that," I said, "except that our users will record incidences of hate. We’ll be working initially to produce a live map—like a traffic congestion map—of more and less racist areas, safe routes home, institutionally racist police forces and local authorities, local populations. We’ll have a star rating system and so on. Eventually I want to roll out iterations for anyone who is not part of the obvious privileged class—for women, for trans people, for people of colour, for the blind and the deaf and so on so that we can map prejudice and racism intersectionally—but one must start somewhere, so I’m calling version one Walking Whilst Black. I have some concerns about the name because I don’t wish to rule out those who are in wheelchairs or mobility carts, but the phrase is there in the language and I feel it is well understood. Available to download next month. About a month after that, we’ll publish our first report into the reality of Britain’s hate at a street level. We’ll be able to tell you who are the most stupid, ignorant, bigoted people in the country to an accuracy of a few metres."
