Something I want more people to be able to recognize is sealioning. Sealioning is a specific type of online harassment that masquerades under a pretense of civil discussion, but is intended to batter and exhaust the target. Thread:

Sealioning is a type of trolling or harassment which consists of pursuing people with persistent requests for evidence or repeated questions, while maintaining a pretense of civility and sincerity.

The troll feigns ignorance and politeness, so that if the target is provoked into making an angry response, the troll can then act as the aggrieved party. Sealioning can be performed by a single troll or by multiple ones acting in concert.

The technique of sealioning has been compared to the Gish gallop and metaphorically described as a denial-of-service attack targeted at human beings.

"Rhetorically, sealioning fuses persistent questioning—often about basic information, information easily found elsewhere, or unrelated or tangential points—with a loudly-insisted-upon commitment to reasonable debate. It disguises itself as a sincere attempt to learn and

communicate. Sealioning thus works both to exhaust a target's patience, attention, and communicative effort, and to portray the target as unreasonable. While the questions of the "sea lion" may seem innocent, they're intended maliciously and have harmful consequences.
