The person you are replying to just pointed out the race of relevant parties.

Come again? First, the post doesn't rise to the level of "accusation." In fact, it explicitly leaves open the possibility that it's a coincidence.

Second, should we just not mention statistically relevant variables? Not report on facts? Do you doubt that race played a factor in this specific case, or that it is often relevant?
