Just by reading the reviews of the people (or maybe the animals) who gave this book one-star, one could tell the emotional vitriol, the name-calling and histrionics that accompany thr so-called "animal rights" movement. The point is that you can't have rational discussions with people who equate the death of six million Jews to the death of six million chickens, which is what these people believe in. And that's the problem - if you disagree with them, you are "ignorant, "stupid" - etc. so if you're a thinking person, take these reviews for what they're worth. That's what's so disturbing about this movement - they use scare tactics, indeed downright terroristic techniques, to get you to "convert" (it's no surprise Hitler was a vegetarian animal-lover!) This book makes a well-argued, nuanced case and perhaps it's attracting so much hate-mail it's because it is quite good. It's easy to read and makes very good arguments.
