Parents were advised ahead of time and about half of the students did not participate. As expected some became ill. Regardless of what animal-rights protesters want to say, it was not.
Human beings tend to be carnivores.
Be it steak, chops, ribs or roast, most of us like our meat. And meat comes from animals. There is nothing wrong with a child understanding the butchering process. And it's totally ridiculous for protesters to muddy the issue with animal cruelty allegations. Killing an animal for slaughter is not done in an inhumane, thrill-seeking manner.
