I know what you mean, but just pointing you're being to much of a pedantic person here.
Yes, toxicity in general is relative, does X cause harm to Y, depends on both X and Y.
But if Y is the general category of human beings. And with what we know as humans and of our feelings and that of others to some approximation. Then we can definitely predict some big categories of very likely to be toxic behaviors such as: shouting, insulting, punching, silent treatment, interrupting, denigrating, avoidance, ridicule, deprivation, personal attacks, lack of consideration, not listening, etc.
These become a pretty simple framework to have an objective measure of toxic interactions.
And that then can be codified into HR policies and societal norms and expectations.
