"I said MOST organisms - and referred to a specific example: kids vs lifespan."

You were obviously not excluding humans, since you then said immediately afterward:

"It appears to be fairly easy to trade kids for longer life - adopt a regime of dietary energy restriction. Very few people do that. I figure they mostly value kids over a long life."

If you had said "most organisms would prefer to die in a few years rather than be sterilized, but humans are different because we have more complex value systems" you might at least have a case, but you're very clearly trying to extent your argument from biology to humans (at least most humans) and it very clearly fails.
