A vegan view requires no amount of anthropomorphizing. It's the traits that humans share with non human animals that makes what we do to them unjust. The traits that make us different are not required, and neither do they justify our treatment of animals.
Emotionally resonating with animals also does not require anthropomorphization. Empathy and sympathy between humans and non human animals is default in most people because of our shared experiences. A lack of is a sign of, at the very least, selective sociopathy, like the kind soldiers might be trained to have in regards to enemy combatants.
Veganism also is not a diet, I think that's important to say. And veganism doesn't create health disasters out of thin air. There's a plethora of nutritional studies backing up how eating with vegan restrictions can be more than adequate.
