This is quite possible, but there is some irony here—you have misrepresented the analogy by describing a three category grouping system by naming two of its categories, implying it is about opposites!
I think that people do this too often in general and that it is implicated in this debate’s confused character. Hence, the analogy with more than a dichotomy of oppositional groups!
Having said that, I find myself agreeing with kurokikaze; the vegetarian-omnivore-carnivore metaphor doesn’t help. The spilt blood (and spilt sap) distract from, and obscure, the “Three, not two” point.

Realising that it is a three-way split, not a two-way split is my latest hammer. See me use it in Is Bayesian probability individual, situational, or transcendental: a break with the usual subjective/objective bun fight.
