status-quo-hater:

It’s really great that so many people are abandoning the word hermaphrodite in zoology, but now we have a new problem. That being the misuse of the word intersex in its place.

Referring to cosexed animal species as intersex perpetuates the exact same misinformation that the H slur does.

What misinformation would that be? The idea that intersexuality is anything similar to the reproductive organization of cosexual species like snails and worms.

Intersex refers to a variation-from-typical in the sex traits of individuals. Examples include calico cats with male reproductive organs, humans with ovotestes, does with antlers, bilateral gynandromorphy, etc

Cosexual refers to a species that had dual reproductive function, such as snails, worms, leeches, etc

These are separate and unrelated things and it is ACTIVELY HARMFUL to conflate them. The H slur conflates them because it is a word originally used for intersex people being applied to cosexual animals. Directly calling cosexual animals intersex DOES THE SAME THING.
