Antispeciesism is at least a two-way road:

A critique of species-ism could mean to completely deconstruct the notion of “species” in favor of finding new approaches to address the groups of beings we now sum up as the group/s of “nonhuman animals”. It can also mean to cling to that idea, that beings can be separated into “species”, only that we position differently towards the beings we’d keep defining in hegemonic terms.
