Sealioning

Akin to playing Devil's Advocate, but worse. Whereas, on occasion, someone playing Devil's Advocate can actually help someone sharpen arguments and make them better, Sealioning amounts to the meme of the little kid replying to every answer with, "Why?" The Sealion has NO interest in hearing any other side, OR of making substantial arguments of its own side. A Sealion will often make empirically ridiculous arguments in the hopes of getting blocked online, which they incorrectly define as "owning" the person who blocked them. In fact, on social media, if you check the Sealion's replies, they're often cut-and-paste replies, frequently 100% unrelated to the topic. The sole purpose is to suppress the free speech of actual people who might thwart the success of disinformation campaigns.
