Earlier quoted context omitted.
People in general look very much like gorillas. They are close cousins after all. Telling humans and other apes apart can't be very easy for a poor, overworked neural network.
Also why are people offended by gorillas, or apes. Imagine being mislabeled as a bear or a giraffe, would people get as offended? What about bring identified as a parrot?
Being mislabeled as a bear on the other hand does not generally carry the negative connotations as calling people apes, so I suspects that this is why CapitionBot is erring on this side of the classification.
