It’s not us a “species” which is disgusting. It’s capitalism and a history of settler-colonialism which enforce disgusting behaviour.

Humans learn through language and culture. Yes at the moment the vast majority of humans blindly follow along in behaving in an abhorrent manner, but that doesn’t mean our fate is sealed or that we’re incapable of change, and building a new culture which encourages cooperative and better behaviour.

It's never the disgusting species — it's always some disgusting bipedal animal with insufficient humanity.
