Animal rights is the most unextreme philosophy I can imagine. It is about nonviolence. It is about compassion. It is about not harming and not causing suffering and not killing when we don’t need to. That is it. It is really, truly that simple.
As long as people will shed the blood of innocent creatures there can be no peace, no liberty, no harmony between people. Slaughter and justice cannot dwell together.
—Isaac Bashevis Singer, writer and Nobel laureate (1902–1991)
