You bring up a good point. WHITES are far more likely to reach the age of 70+ than BLACKS (many reasons for this, not worth getting into here)

So because black people are younger on average and since the "virus" kills mostly old people, simple statistics would tell us a HIGHER percent of white people should die (out of total white people) than black people (out of total black people)

So it's highly unlike this douchebag misspoke, because it wouldn't make any sense
