I made the choice to be vegan because I will not eat (or wear, or use) anything that could have an emotional response to its death or captivity. I can well imagine what that must feel like for our non-human friends - the fear, the terror, the pain - and I will not cause such suffering to a fellow living being.
Ethical veganism results in a profound revolution within the individual; a complete rejection of the paradigm of oppression and violence that she has been taught from childhood to accept as the natural order. It changes her life and the lives of those with whom she shares this vision of nonviolence. Ethical veganism is anything but passive; on the contrary, it is the active refusal to cooperate with injustice
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.
