It really isn’t, it’s the scientific term for a feature in a whole bunch of animals…
Like holy shit context matters, and I don’t mean that in a “it’s fine if it’s not meant as an insult” way, because people have a right to ask to not be referred to a certain way regardless of intent.

That line in particular isn’t an ideology, it’s a fact. Committing murder is illegal, but if I want to, I can still murder someone. More generally, systems can be put into place to prevent behaviour, but anyone can still try to get around them.
(I’m not a full on anarchist since it doesn’t seem practical but I do agree with many of the ideals.)
