Actually, I'm trying to understand this article by Eisel Mazard:http://a-bas-le-ciel.blogspot.com/2012/06/vegetarianism-and-theravada-orthodoxy.html
What does the Buddha say about vegetarianism? The first part of the answer is that you need to know where to look (in the texts) for the answer, and, just as important, you need to be keenly aware of the excuses and misdirections that will distract you from what the texts say (and what they don't say). The second part of the answer won't be found in this article: anyone can work with the raw materials themselves and, in writing this blog, I am refusing the role of the guru (i.e., I'm not offering any easy answers, just answers).
The author seems pretty sharp, and I believe he is a vegan, so presumably he feels that at least vegetarianism is supported by the "raw materials", but I found the article kind of confusing, and I don't know Pali so I can't really work with the raw materials. I thought by having a list of all the references to meat eating in what he calls the "core canon" I could at least begin to see what he might be getting at.
