A more charitable version of this argument would build in a series of degrees as to how likely those denigrations are to make stochastic terrorism occur. For example, vague insults directed at a group of people are less likely to cause terrorism than ones associated with a single person. Insults that come loaded with implicit threats (like doxxing) are much more likely to cause stochastic terrorism than those without. Insults and threats against groups who are marginalized in society are more likely to cause terrorism. Insults made in a space full of mentally deranged people are more likely to cause terrorism.

With all of this, it's clear that if you're going to argue that stochastic terrorism even exists, you should believe that it is happening at Kiwi Farms. Incredibly personal, incredibly specific (doxxing), directed at marginalized people, and in a space full of people that are already predisposed to acts of violence.
