I find it very annoying that so many animal advocates talk about the difficulty of being vegan. Many animal advocates are inclined to make the issue their suffering and not the animals' suffering, and I suppose that accounts for part of the reason that veganism is portrayed as such a "sacrifice." And many animal advocates are not vegans, or are "flexible vegans," which means that they do not observe veganism at all or not consistently, and emphasizing the supposed difficulty of veganism is part of justifying their own behavior.

Ethical veganism represents a commitment to nonviolence.

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.

To say that a being who is sentient has no interest in continuing to live is like saying that a being with eyes has no interest in continuing to see. Death—however “humane”—is a harm for humans and nonhumans alike.

We can no more justify using nonhumans as human resources than we can justify human slavery. Animal use and slavery have at least one important point in common: both institutions treat sentient beings exclusively as resources of others. That cannot be justified with respect to humans; it cannot be justified with respect to nonhumans—however “humanely” we treat them.

It costs us so little to go vegan. It costs animals so much if we don't.

We proclaim human intelligence to be morally valuable per se because we are human. If we were birds, we would proclaim the ability to fly as morally valuable per se. If we were fish, we would proclaim the ability to live underwater as morally valuable per se. But apart from our obviously self-interested proclamations, there is nothing morally valuable per se about human intelligence.
