为了救一个生命而牺牲另外一个生命。
PETA 的副总统 MaryBeth Sweetland 有糖尿病而必须定时打(经由动物测验发明的)胰岛素。
当她被问及时, 她回答
"I'm an insulin-dependent diabetic. Twice a day I take synthetically manufactured insulin that still contains some animal products -- and I have no qualms about it ... I'm not going to take the chance of killing myself by not taking insulin. I don't see myself as a hypocrite. I need my life to fight for the rights of animals."
--Glamour, January 1990"
我的生命比动物生命重要。
