But you're reasoning about an individual based on characteristics of a population.

That's pretty much the definition of bigotry: prejudice against a group or against an individual on the basis of their membership in a group.

You could just look up Wax's record.

Also, you didn't bother to account for Wax being female. And a professor, not in a Fortune 500 company.

That Fortune 500 companies are dominated by white men is really no cause for you to disparage Wax. If you want to criticize Wax's actual record, go for it. If you want to criticize Wax's statements, go for it--goodness knows you can find enough there (though a lot of it is less outrageous in context than out, you can find enough that is outrageous even in context).

If you want to malign individual people on the basis of statistics, you're acting in a bigoted fashion. Same as when people disparage black men on the basis of the statistical reality that they're more likely to be murders.
