Vegetarianism as a moral position is no more coherent than saying that you think it morally wrong to eat meat from a spotted cow but not morally wrong to eat meat from a non-spotted cow.

All sentient beings should have at least one right—the right not to be treated as property

We do not need to eat animals, wear animals, or use animals for entertainment purposes, and our only defense of these uses is our pleasure, amusement, and convenience.

Being vegan is not a matter of "lifestyle." It is a matter of fundamental moral obligation. Is being vegan a matter of "choice"? Only insofar as we are able to choose to ignore our moral obligations not to exploit the vulnerable.

...eating animals involves an intentional decision to participate in the suffering and death of nonhumans where there is no plausible moral justification.

Domesticated animals such as dogs and cats are vulnerable and entirely dependent on us for all of their needs. They live very unnatural lives because they are not part of the human world and they are not part of the animal world.

I certainly believe that we have a moral obligation to care for the dogs, cats, and other nonhumans whose existence we have caused or facilitated as part of the institution of 'pet' ownership. But I maintain that we ought to abolish the institution and stop causing or facilitating the existence of more 'companion' animals.
