I’ve enjoyed Rutherford’s work before; he communicates clearly, and he’s clearly delighted by the intricacies and weirdnesses of DNA and inheritance. In this book, he tries to provide people with the tools to argue back with some key racist talking points about skin colour, intelligence, milk-drinking, ancestry and proficiency at sport. For the most part, he doesn’t argue with a specific study or source of an idea, but offers up general points. It’s actually a very ineffective way to argue with anyone who’s going to ask for evidence, however true his points are; you can explain to a horse how to get to the water, but it’s not going to go and drink no matter how long you talk at it. Or, as my grandmother says, “You can’t educate pork.”
Really, the main problem is that some people are never going to believe you, even if you can talk the hind leg off the proverbial donkey and you can provide the sources. It’s not really clear who benefits from this book — mostly, I guess, people who know people who are sat on the fence, but can listen to reason. If you know any of those, I’ll send you my copy (assuming I haven’t already sent it to someone else) and best of luck to you!
It’s still clear and engaging, but preaching to the choir (by definition, if it’s aimed at people who want to argue with racists) and without a really clear guide to how to use these talking points. Vaguely replying “yes well everyone is related to everyone else if you go back through the family lines to the 16th century” doesn’t cut it for most racists.
If you’re on the fence and you want to understand why Ashkenazi Jews aren’t inherently more intelligent than other people and African runners aren’t inherently better at sprinting than anyone, it might be useful!
