That's the awkward thing about life as a member of a species--you really don't matter existentially, and yet if you have to pick one feeling for everyone to have, everyone had better feel that they do or it is indeed an existential disaster.

So, yes, it is often used as a scare tactic because it's misapplied at the individual level (where there is profound room to accommodate and even benefit from variability). But here the advice is universal, and the error is backwards: you cannot generalize sensible individual advice that is sensible because of the room for individual variability within the population as a whole and always get sensible universal advice, because at that point the variability one was counting on to make the argument has collapsed.

So it pays to be circumspect in just how strongly one advocates for llama-indifference.
