I honestly think they really don't know the difference between "race" and "species" and think they're on the same level, rather than nested for some reason. You hear that nonsense "there's only one race - the human race!" ... oh, so, humans are just one breed (race) out of a bigger species that includes chimps and bonobos then? People hate it when you point that out (and then the same people will berate anyone who feels scandalized by being related to a genuine reeing retard for some bizarre reason.)
