>"Because giftedness is not to be talked about, no one tells high-IQ children explicitly, forcefully and repeatedly that their intellectual talent is a gift. That they are not superior human beings, but lucky ones. That the gift brings with it obligations to be worthy of it."

Thankfully. High-IQ children know they are high-IQ; if they can't figure out how smart they are, they aren't very smart. They don't need to be told they're special, though. We need people who live intelligently rather than live for the purpose of being intelligent.

Telling an intelligent person they are obliged to use their intelligence in service to others is the quickest way of convincing him or her not to.

>Apparently, most people who are vegetarians don't necessarily believe that it's not okay to slaughter other animals for consumption.

That's quite true. Most vegetarians have adopted their eating habits out of health related, not ethical, reasons. Those with ethical concerns are "vegans", and their diets usually go beyond vegetarian restrictions. This, of course, is a gross generalization.
