I'm not a vegetarian. Now, don't get me wrong - I like animals. And I don't think it's just fine to industrialize their production and to churn them out like they were wrenches. But there's no way to treat animals well when you're killing 10 billion of them a year. Kindness might just be a bit of a red herring.
