My specific argument is with you comparing differences in dog breeds to phrenology. I'm not saying that dogs of a specific breed are more aggressive; Im saying that comparing dog breeds on a morphological level is not the same as comparing human races on a morphological level. Phrenology is a pseudoscience specifically because human races do not vary morphologically, especially not in skull shape. You can easily measure a dog's skull to tell a Great Dane from a Chihuahua, which is why I used those breeds as an example.
