Terrorism", which probabilistically results in violence against certain groups...here's an excerpt from the attached Wikipedia description of the phenomenon...
------------------------
According to this framework, originators deploy hostile rhetoric toward identified out-groups while avoiding explicit calls for violence. Amplifiers repeat and spread the messages, causing some receivers to internalize the content and take action once a personal threshold is reached. The rhetoric frequently frames targets as existential threats and may use coded, joking, or ambiguous references to violence; particularly within echo chamber environments, this repetition can stoke anger, contempt, and fear. Scholars describe the central dogma of stochastic terrorism as probabilistic: when hostile, dehumanizing, or threat-framed rhetoric is repeatedly amplified to mass audiences, it elevates the background risk of ideologically motivated violence by unknown individuals over time, even though who acts, when, and how remains indeterminate and uncoordinated.[1][2][12]
------------------------
Again...witness the motivations of those mass killers in Buffalo (against Black People)...and in El Paso (against Hispanics)...both of the perpetrators harbored deep hatred of those groups. Such chat groups can indeed push some unknown individuals "Over the Edge". Lesson:...don't engage in hateful speech...especially in mass/social media.
