Oh, face it, they're setting it up so that "racist" means "white", so when they say they're going to "do something" about "racists", it's not going to alarm the dumb herd too much until it's too late and they're already having their light skin, hair and eye colour selected out of the population by the monophenotypic majority. The wild rats are coming after the domesticated, and they have no problem telling the difference from looks.

(Domestication causes changes in coat and eye colour. Domesticated races always have more phenotypic variety than wild ones.)
