This sentence:

> But if you've ever rubbed a wild baby whale's nose while looking at it in the eyes -- and experienced the emotional connection which results -- then you will be forever incapable of hostility, apathy, or utilitarian thinking about whales.

Comment you're replying to is saying that this is optimistic; most people are capable of doublethink, and will quite happily "love" one individual of a species while being completely indifferent to the death and suffering of the rest of that species. I've observed the same phenomenon.
