Sometimes, the exact same set of words, presented in different environments, could be considered trolling or not trolling.
For example:
Attending a black lives matter event with public speakers and a Q&A session.
You would be trolling by asking the guest speaker to address the fact that white people are disproportionately victims of police violence, per reported rates of crime victimization, compared to black people (meaning, people report being victims of crimes from black people more often than people report being victims of crime from white people - and the rates still show similar ratios across geography, race, and age - and when you represent police violence against those groups, white people are overrepresented meaning police are more likely to confront white people with violence than black people based on rates of occurrence. This is a much different narrative than you are commonly told and the data is far more complicated than "black people are harmed more by police." It's not that simple. Never is.), you MIGHT be trolling. You MIGHT be met with tons of anger.
However, bring up the same topic in an academic setting where police are attending the class as part of a program, you could help the police, perhaps, mete their violent actions against white people. Maybe you could reduce the amount of police violence against white people by having this frank conversation.
It doesn't matter that you're using facts. One forum, it's clearly trolling. In another forum, it's to help influence positive change and have a meaningful discussion.
