I admit I didn't know "sealioning," which sounded like it came from the same mindset that gave us "mansplaining," and sure enough, it is:
the name given to a specific, pervasive form of aggressive cluelessness, that masquerades as a sincere desire to understand
At least you should get your own jargon right. You're free to think me clueless, as I am to think the same of you, but there's nothing I've written here than connotes false sincerity. Arrogance, yes, impatience with narrow politicized thinking,yes. But the closest thing to false sincerity appears in your inability to admit that you made a bad comparison between Plummer's non-fictional essay and a completely unrelated fictional comic by Sophie Labelle. And once your mistake was pointed out, you assumed a pose of sincere disdain for anyone who chose not to acknowledge your supposed wit-- thus, "making it all about you."
By the way, can anyone explain to me why advocates of queer theory (as Plummer must be, since he's queering Dick Grayson) are so in love with Frederic Wertham? Isn't this the guy who was warning American parents about how their children were going to be corrupted by those evil comic books, which presented salacious images of smooth rich men luring young men into decadent ways? There's a word for people like Freddy Wertham, and it does have the word "queer" IN it, but it isn't "queer theorist." (HInt: the last part rhymes with, "tater.")
