Matt, if you haven't seen it, check out this post: Of Triggering and Triggered, Part 4 (The whole series is good, if long)
Offence Trolling
A ‘troll’ is a person who exposes others to offensive or inflammatory material in order to produce an emotional response generally in order to sabotage or prevent conversation. While trolling is typically thought of as a hostile action, explicitly calculated to offend the trolled party, there is a commonly ignored but exceedingly widely practiced form of trolling which functions quite differently. This sort of trolling – which I term ‘offence-trolling’ – involves the trolling of one’s own community. Like other forms of trolls, offence trolls use material calculated to be offensive and inflammatory in order to provoke an emotional reaction and to derail debate. However, the offence-troll does not seek personally to offend their community, but rather purposefully seeks to offend and provoke an emotional reaction in their community by means of the sharing or reporting of the words or actions of another party.
The offence-troll will typically take an extreme or ill-worded statement of their opponents, wrench it from context, put the worst possible construction on it, and present it to an audience carefully primed to take extreme offence to it. The emotional reaction, offence, and outrage can then be leveraged against the opposition, helping to push them out of the debate, and relative to the wider society, capitalizing on the offence to gain greater support and concessions. While the offence-troll may claim to desire to protect the weak and sensitive from offence, their real goal is to use the offence that results when the weak and sensitive are exposed to sharp, muscular, and combative discourse to get their way. The goal of the offence-troll is to ‘trigger’ others and thereby to accumulate the social capital of offence.
