If one takes the position that all animals are sentient individuals, and that they “all have an interest to live and not suffer,” then it makes sense to avoid harming them as much as possible. So why promote a “reduceitarian” diet, rather than veganism?
I recognize that some people have genuine practical obstacles to removing all animal products from their diet (and wardrobe, etc). But it makes no sense to tell people that all chickens feel pain and want to live, and then say that it’s fine to eat chickens several days a week. Same goes for eggs, the farming of which result in just as much death and suffering (virtually all male chicks are killed just after hatching, whether the females end up on a so-called “humane” farm or in a backyard).
If we are to take the moral worth of animals seriously, we cannot say that’s it’s OK to kill and eat them part-time in the absence of genuine need. Not everyone can go vegan immediately, but promoting “reduceitarian” and vegetarian diets and “Meat Free Mondays” conveys the impression that human pleasure and convenience are more important than non-human lives.
