DON'T BUY FROM AMAZON!!!
Did you know that Amazon.com sells materials on dog fighting? I don't just mean documentaries. I mean things that will help you raise and train dogs to fight. They encourage the disgusting, illegal practice of making dogs fight, injure, maim and kill each other. For this reason, I stopped buying from Amazon a long time ago. I also sent a note to their CEO, but I never received a response.
I just went back and checked their website. They still sell this disgusting material. Lest you think I'm kidding, let me share a listing with you: The Dog Pit - Or, How To Select, Breed, Train And Manage Fighting Dogs.
In case dog fighting isn't enough, they also offer The Breeding and Management of Fighting Cocks.
Before anyone cries censorship... well, okay, in some way, what I'm suggesting is censorship, but businesses are free to do so. This is very different from government action. While I'd never suggest it for most things (like divergent political views--heck, I'd even protect the right of that evil woman Ann Coulter to have heard books sold), when a practice is so abhorrent that it's illegal and constitutes cruelty and brutality to animals, then materials that aid it shouldn't be sold!
Anyhow, DON'T BUY FROM AMAZON!!!
