I have previously written about Gary Francione, of whom I am a fan. Gary offers a consistent message about animal rights that aims to protect animals long term (as opposed to an animal welfare approach). His blog, Abolitionist Approach, is great and I always enjoy each post.
Now you can check out an interview with Gary Francione, by The Vegan News, on YouTube. Here's the first video below. You can find the rest of them alongside this video on YouTube, under "related videos."
