How about:

1. Someone who, following an honest best effort to evaluate the available evidence, concludes that some of the beliefs that nowadays fall under the standard definition of "racist" nevertheless may be true with probabilities significantly above zero.

2. Someone who performs Bayesian inference that somehow involves probabilities conditioned on the race of a person or a group of people, and whose conclusion happens to reflect negatively on this person or group in some way. (Or, alternatively, someone who doesn't believe that making such inferences is grossly immoral as a matter of principle.)

Both (1) and (2) fall squarely under the common usage of the term "racist," and yet I don't see how they would fit into the above cited classification.

Of course, some people would presumably argue that all beliefs in category (1) are in fact conclusively proven to be false with p~1, so it can be only a matter of incorrect conclusions motivated by the above listed categories of racism. Presumably they would also claim that, as a well-established general principle, no correct inferences in category (2) are ever possible. But do you really believe this?
