I was reading an article about Peter Singer, and I was surprised about something. He is not a full time vegan. He says he only buys vegan products for himself, but he will eat lacto-ovo products when he is at a friends house or when he doesn't have a choice in other circumstances. What do you think of this? I'm on the fence. I think you are vegan or you're not. At the same time though, he isn't directly contributing to the massacre.
