Admittedly, I was wrong to say that she said any group was better than the other. And it's true that differences do exist between groups on average. However, humans have used group differences - real or imagined - to justify horrific abuses and that hasn't changed. So, I think it's a valid concern to keep in mind when talking about these things. But I would ever say that Wax should be cancelled for merely bringing up the topic of group differences.
