Possibly the most racist thing that Quillette employee Bo Winegard has said yet

We know that when Winegard uses the term "group differences" he means race.

Now so far there's no evidence that Caliper Claire Lehmann approves Winegard's tweet. On the other hand there's no evidence she has any intention of firing him from Quillette. The reason why is most likely because she agrees with him. 

And that's what Quillette is.
