I find it genuinely interesting that it's entirely possible to have the debate that there are genetic differences in DNA passed down through generations without it descending into "you're racist" claims.

Feeding back into the main topic, another issue with the study may well be that any potential genetic differences may well not be factored in. For example, if they find black wingers more likely to be called "quick" etc, then those fast twitch muscle fibres could very well be a good reason behind commentators using the phrase more for them.
