Sealioning

Marsh lists sealioning under being deliberately obtuse, one of the tactics used to exhaust a movement from inside, and gives the online name along with its origin in a Wondermark comic she says described it perfectly. The mechanism is demand rather than disagreement. Nothing is refuted and no position is taken, and the group's energy goes into explanation instead of action while the demands renew themselves indefinitely. Two features make it effective. It is personal, since the requirement is that things be explained to this person specifically rather than that an explanation exist, so published material does not discharge it. And it inverts responsibility, since failure to satisfy the demand is attributed to others being unclear or complicated rather than to the demand being unsatisfiable. The in-person version usually involves demands for more hands-on and personal explanation and mentoring, which is harder to recognize because it resembles an ordinary request for help. Marsh places it in a list with fearmongering, aggression, devil's advocate and insistence on discussion, and the family resemblance is the point, since all five convert a movement's capacity into talk. Her remedy for the adjacent tactic of bikeshedding applies here too and it is awareness rather than argument, since once everyone can recognize the pattern they are more likely to prioritize the important work instead.

The term comes from a 2014 Wondermark strip by David Malki, in which a sea lion pursues a character demanding evidence with relentless politeness, and it entered wide use in online argument. Research on online harassment describes brigading and coordinated question campaigns performing the same function. Sartre's observation about antisemites arguing in bad faith, delighting in the game rather than the argument, is an older statement of the underlying dynamic. Marsh's contribution is placement rather than naming, since putting it in a list of movement sabotage tactics reframes it as an organizational problem to be recognized rather than an interpersonal annoyance to be endured.
