> But not the same level of anxiety about “what if I don’t exist, or my species or bloodline” doesn’t go on.

To some extent, sure. But I think some of this is us habituating to pets who were sterilized prior to puberty. In post-pubertal animals the drives to have and rear children are pretty strong.

> We are not “special” at all. We have no right making other species go extinct

That is self contradictory. A lot of species go extinct due to other species.

If we don't have that "right", that makes us special.

Rights are a fiction we made up for our own benefit, like money and the abstract concept of fish.

So is the concept of "fiction" made up too?

Dunno. As distinct from lies? Perhaps.

IIRC early Christianity thought acting violated the ten commandments, and some fiction writers today say their job is to tell lies for money.

You missed my point

That comes across like "for more information, please re-read" on a Scarfolk Council poster.
