I read this a while ago, and I had the devil of a time finding the site
again to share here.

This is an excellent and thorough elaboration of why "veganism" fails as
a sound ethical approach to the human use of animals. I really like the
author's turn of phrase, "the vegan shuffle." By that, he means the
flip-flop back and forth between animal "rights" and the reduction of
animal suffering when "vegans" are confronted with the inescapable and
undeniable fact that "veganism" is not a reliable means for achieving
either one.
