I agree fully. If you were not allowed to eat other life, you would be left with licking salt. But that's not what I meant. What I meant was people use the "thing" label to make it easier to drop empathy - to do shitty things to both humans and other animals.
Violence is not the basic force driving life and decisions. It's just one of the basic factors that helps to structure our society (and all societies).
By treating animals like people, do you mean respecting them and not killing them or letting them work as senators?
IMO treating animals like things is definitely wrong, in the same way treating people like things is. Neither of them is a thing, all us animals are alive.
Only some people are something - like Jews during WW2. We call living creatures including people "things", because then it feels more ok to kill them. It lowers the empathy.
It justifies it by precedens. Aster means star - astronauts have been called people travelling to stars for a long time, even though interstellar travel is not possible for us yet, so naming their means of transport Starship is not out of line. It just follows a kind of funny naming tradition.
Ok, now try with hawkweed.
