It's unfortunate such a video has been put up on this website but everybody makes mistakes and everybody is searching and I've been through this before. Open minds are wonderful, but there is a thoroughness and diligence to study and research before you accept any ideas. This video is designed to drive home conclusions based on an appeal to the emotion and pre-fabricated and twisted facts. it's a really bad example of agiprop and how effective it can be. and I don't know about part two and part three, I definitely know that this part one on religion oscillates between irrelevance (yeah so?) and made up nonsense. I don't care what people believe but I hope they do enough thinking for themselves, based on actual research and scholarship. Also I myself wonder what this has to do with nutrition. Check out some of the criticisms on the wikipedia page if you are interested :)
