The term toxic is nearly useless
Nothing of value is shared when a person uses the term toxic within the context of identifying player behavior. Calling another player or community toxic is akin to saying "they hurt my feelings." But your feelings aren't my own and neither are your sensibilities. Labeling somebody toxic is a vain and futile attempt to transform your person-relative opinion into a fact.
Instead of throwing around the word toxic, why don't you explain in detail what your issue is and make an argument?
