I'm of course unable to prove anything about my behavior.

That, however, is besides the point in my opinion. All taxonomy is arbitrary; there aren't "races" or "species" or even distinctions between "mineral" and "organic". All that matters is that those artificial distinctions are meaningful to us, humans.

In that sense, we consider we humans are qualitatively different than plants, and a Venus flytrap is closer to a plant than to an animal.
