Almost as if toxicity of a person is an integral part of their nature and politically correct spaces are detrimental to the discourse.
Obviously, most people hold beliefs of some form, and those beliefs will clash with others. Bandying around "toxic" as an absolute in those situations is narrow-minded and prejudiced. Reasonable people with contributions in one neutral area and one controversial area are lumped with this same label as trolls, doxers, and inciters of violence.
Specificity of labels is very important, especially when they are tied to consequences.
Where "toxic" can certainly be used is in relation to a certain goal, like reasonable level-headed discussion, or subscription to a certain worldview; instead of as absolute. Even actions like deliberate trolling aren't considered toxic on sites like 4chan, because that's part of their accepted and promoted culture.
