I think you can always find ways to show the definition might conflict with making ethical choices; after all it isn't perfect, the world is not perfect, nor are we perfect. My point is that when you get down to it, there has to be a reason why veganism says don't eat meat, or don't exploit animals, etc. The reason is that we can have moral concern for other animals and veganism is saying just what that concern is. It doesn't say "love all animals", or "ensure all animals have a good life", or "be kind to animals". It makes quite specific claims - that our moral concern is that of fairness and justice for other species
when our actions can affect them.
Various advocates and ethicists have come up with different ways to frame this, for example Singer's equal consideration idea, or rights theory, etc. But all simply come back to the basic idea of fairness and justice. Fairness in this context means to take into account the interests of other species, and justice means to do that consistently. Veganism is as far as I know the only broadly encompassing term that reflects that commitment and the consequent practice by saying that we should have such moral concern for other animals. Personally, I'd like a better term because veganism is now quite corrupted in the public perception, but why invent yet another word? The idea underlying veganism and all the other formulations is essentially the same.
My position on all of this is to propose that veganism is the ethical framework, the basic system of ethics, that extends moral scope to include other, sentient species when we can and that its core proposition is that of fairness to other animals. Everything flows from that, including rights theory. In terms of rights, fairness and justice can be expressed as aiming to respect the basic rights of other animals to their own lives, to be free, and not be treated cruelly. The exact same rights we respect for human beings. In terms of the Vegan Societies definition, fairness and justice are implicit in exactly the same terms - the wish to prevent the exploitation of other animals (ie to be free and able to live their own lives) and to not be treated cruelly.
This is what I am getting at. The "philosophy" - the underlying idea - is that of moral concern for other animals, something that by and large other species don't have. You wouldn't have adopted strays or stopped eating meat or whatever without that. It is the only thing that can lead you to care for the animals just for being themselves. Or, as I put it, to recognise the inherent value and dignity of other species and therefore want to be fair to them. Farmers treat animals well in many contexts, but they aren't really doing this only from the need to respect the animal's dignity but to ensure maximal efficiency and productivity. They even tell you that - a stressed animal will not provide maximum return. And that is exploitation in the sense that the vegan definition is exposing.
So my take is to advocate to others that veganism just IS what it means to worry about other animals for themselvs and strive to make fairer choices when I can. Those choices can be positive (by doing something) or negative (by not doing something). It doesn't matter which because what matters is context, my personal circumstances and what I am able to do. Veganism is all we need to describe the best, most rational and most effective ways for humans to interact with other, sentient species.
I tried to sum this up simply in a recent blog post:
Several critics have taken us to task for promoting veganism when we say we are about justice for other animals. Their reasons seem to stem from a belief that veganism is an anti-human, rigid and u…

My question here is whether this makes sense or is there another general term/concept for this that you know of. Not even necessarily veganism but perhaps some other ethical theory. I just do not know of one.
