Yes. That is precisely what I’m arguing. They are a contradiction of terms. Mutualism is when both organisms prosper from their relationship. Parasitism is when one organism prospers at the expense of the other. There is zero overlap between those two things. If both organisms are prospering at least a little, that is mutualism. If only one organism is prospering, that is parasitism.
Like, am I taking crazy pills here? Or are you just stupid?
