Did you actually measure that statistic, or did you just make it up so that you could trash it and, for that matter, all other statistical analyses you disagree with?
This particular correlation is not implausible if you consider that (obsessive) tidiness is related to a particular way of viewing how the world ought to be -- everything in its place, and so on. And maybe if you have that perception quite strongly in one aspect of your life a similar desire for order might leak out into other parts.
Or maybe that's me projecting order and meaning onto something that has none. But it should be easier, at least, to see that a link *may* exist here, as opposed to between drunk drivers and underwear colour.
In any case, what's certainly true is that being tidy itself doesn't have anything to do with racism, ie there's definitely no causal link from one to the other. If there are correlated, then it's because of a common factor that can be responsible for driving the two behaviours.
