Related thought: people having different definitions of “justice”, where that word points to overlapping-but-not-identical clusters of moral intuitions.
Animal welfare maps best on a cluster like “concern for the least-well-off” or “power for the powerless” or “the Rawls thing where if you imagined it happening to you, you’d hate it and want to escape it” or “ending suffering caused by the whims of other agents.” That last one is particularly noticeable, since we usually have a moral intuition that suffering caused by other agents is basically preventable-thus-more-tragic.
