If you are in the process of learning about veganism or you've heard the term "abolitionist" and don't quite understand what it means in relation to veganism, you should go and read Gary Francione's new pamphlet. It is a short easy read packed with tons of information. It is a tri-fold pamplet so reading order is top right panel, bottom page, top left 2 panels.
This is also a good read if you happen to be one of my friends (or my mom) who doesn't quite understand why I am vegan.
If after reading the pamplet, you still want more to read, check out Gary's FAQs.
