Actually, kids can have lousy consciences too - if my experience burning ants is any indication.
My experience as a parent reinforces a tabula rasa view of children. They don't have much of a conscience, either way. Its something they learn, constantly, from their environment.
If, say, a 5 year old doesn't want to eat something because a poor animal was killed its most likely this is a message they picked up from someone or something. It may be as simple as it reminds them of a cartoon animal character. But its not because of some inherent human sensitivity toward animals.
More on-topic. Man is, by nature omnivorus. Its normal and natural for a human to eat meat. This inherently means animals must die.
Now, that doesn't mean that humanity doesn't eat too much meat or that we couldn't deal w/ animal husbandry in a more humane fashion. And, yes, there are healthy alternatives for protein. Sure. You bet.
But, that's not what PETA is after. They have some moral stick up their a$$ that people should not eat animals period. And, then, they try to make their point through all kinds of ridiculous behaviors, from the simply stupid to the highly illegal and dangerous.
