For the record Websters defines Sealioning thus Sealioning refers to the disingenuous action by a commenter of making an ostensible effort to engage in sincere and serious civil debate, usually by asking persistent questions of the other commenter. These questions are phrased in a way that may come off as an effort to learn and engage with the subject at hand, but are really intended to erode the goodwill of the person to whom they are replying, to get them to appear impatient or to lash out, and therefore come off as unreasonable. Your question "Have you been polled?" Is an example of sealioning. You don't actually want to know if I have been polled. You don't think any possible answer would illuminate the discussion. You don't intend to make any actually arguments to the validity of polling other than a casual dismissal. You have no intention on engaging in any actually substantial debate or discussion. I started this subthread with substantial points with sources. Answering a manipulative insincere question with a reason why the question made no difference isn't itself sealioning.
