By that logic any smaller predator that feeds on small animals is a “cat” and any large predator that feeds on larger animals and/or hunts in packs is a “dog” which is… Not at all how nature works. Foxes are canines that exhibit a lot of classic canine behaviour and very little cat behaviour in top of many behaviours unique to foxes, domestic cats are not actually solitary creatures just solitary hunters hence why they develop colonies, some wolf species are solitary hunters such as the maned wolf, birds of prey also fill the same ecological niche as cats, as do weasels, chimpanzees are also apex pack hunting mammals too but no one would ever say they’re running “dog software”, heck humans are the ultimate Apex pack hunting predator, does that mean wolves are just running “human software”? Lions and hyenas exhibit completely different behaviours and social structures from both domestic dogs and cats as well as each other, lions also aren’t the only large cats that hunt in groups, cheetahs can as well when they form a coalition. It just seems like a dumb way to classify animals as if dogs and cats aren’t extremely diverse and complex animals in their own right and instead every member has to be forced into these awkward and inaccurate “hardware vs software” stereotypes.
No I don’t think people who use the word “digger” are specifically and purposefully altering the N word and directly referencing it.
