PETA is a propaganda organization whose stated goals are to end all human dependence on and use of animals. They spend less than 1% 0f their budget on actually doing the things they seem to get credit for here (by their own figures). Comments here seem like praising the Natzis for making the trains run on time.
Their are plenty of organizations who promote the humane treatment of animals, who actually do something, starting with your local humnane society, and I don't mean the Humane Society of the United States which is barely one cut above PETA.
