You were very clearly referring to that specific scene as "tongue-in-cheek," so I debated your word usage you on that specific scene...at what point did I "miss the whole point"? I'm not the one who spun things off here...even though I don't think word definitions are usually something you can just agree to disagree on, I was fine with leaving it at the initial correction. But you decided to argue about it, and when other people jumped in, you went off on some tangent about Joker as an antithesis to Batman, which nobody was talking about in the first place. So much for "that's that."
You rants aren't subversive, they're just wrong sometimes. Which is fine, we're all wrong at one point or another, but you should expect to be called out on it when you are.
