It's fascinating how visceral the reactions are when someone introduce a comparaisons between humans and other animals, that doesn’t start with the conclusion that humans are superiors anyway.

There’s reflections done around the term Speciesism (and anti-speciesism) and most people today stands for speciesism.

Interestingly the reflection is close to the debate on racism and anti-racism (where most people settled to anti racism to the point there isn’t much debate anymore), but race is only an informal classification that don’t hold much meaning in biological term, contrary to species.
