Figgs isn't knocking meat eaters. He is knocking meat eaters that he thinks don't need to eat meat. Any way you cut it, you can't get around the fact that the meat industry in the US is an abomination-from an ethical standpoint all the way to a downright physical standpoint with it's clear and observable affect on the environment(go ahead and get a sample of ground water down the street from a factory farm and find out for yourself).
Having said that, I wrote a research paper on this subject and think that humans are designed, at least now, to eat meat...although, only raw meat. And definitely only sustainably farmed or wild meat.
