This visualisation implies a kind of discursive toxicity, where 'toxicity' is used metaphorically to indicate a dangerous or debilitating character. Its inclusion attempts to stretch understandings of 'toxic', and how the term can be used more broadly than it has been, to productively describe discourses and relationships.
This visualisation speaks to toxic discourses that can pose as 'progressive' but really conintue structural harms and injustices against particular parts of the population.
