I’ve definitely heard speciesism used both ways, but I think it’s usually used without much reference to an exact view, but as a general “vibe” (which IMO makes it a not particularly useful word). But, I think people in the EA-side of the animal advocacy world tend to lean more toward the “it’s discriminatory to devalue animals purely because they aren’t a member of the human species” definition. I’d guess that most times its used, especially outside of EA, it’s something more like the “it’s discriminatory to not view all animals including humans as being of equal value” view but with a lot of fuzziness around it. So I’d guess it is somewhat context dependent on the speaker?
