> 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.

Never heard sealioning before, "thanks, I hate it" I guess. Reminds me of "dog-whistling", and in a way is an exact example of what PM_me_your_math is getting at.

You can decide someone is being disingenuous, but if you can't demonstrate that somehow, I'm inclined to disbelieve you. The GP said "those claims are demonstrably false", and then a follow up comment said "okay, please demonstrate", and you can claim that's being disingenuous? Don't you see how that creates an iron-clad thought bubble?
