Veganism is not only related to food, it is conscious decision to lessen the unneeded suffering and exploitation of animals. Which includes using them for food but is not limited on food. People on carnivore diet do not have that overarching ethical stance which guides their decisions. So saying "people don't have to go full blast vegan" is not the same as "people don't have to go full blast carnivore" because people rarely go vegan because of the diet, they do it because of the animals. Doing it only because of the diet would probably be called "plant based" eating now a days.
