Nuts to protein scaremongers

We vegetarians have made and heard countless arguments as to why a meat-free diet is healthier, and here is another one to throw on the pile. It's all very official and quite good at reposting those who fall lazily back on the not-enough-protein line. We need protein to grow big and strong and aggressive, of course, but how much? Meat eaters are always fondly recalling the days when we used to roam the earth with spears looking for animals to kill. But how many did we actually kill? I don't know, but I doubt there was roast on the cave menu every night. So we had sharp teeth, granted, and we ate meat, granted, but not all the time. Anyway, time we moved on from the Stone Age, don't you think?
