How do you get to declare them "wrong"? It's a two way street right? Or, is it a one way street - your way?
Pretty much any post modern interpretation of any work pretty much says that authorial intent is largely unimportant. I mean, this is English 101 stuff. Any first year university student can tell you the same thing. The notion that the author is a sole or even important element in interpretation died decades ago.
You can disagree all you like. Free country and all that. Doesn't matter. When the author steps up and says, "My work means X", his or her word is no more important than anyone else's. Support your interpretation with the work. If the work supports your interpretation, fair enough. But, even if it does, that's not the only interpretation possible and if someone else can look at the work and support a differing interpretation, your position as the author grants your interpretation absolutely no more value than that other interpretation.
Like I said, it's just so bizarre to see someone try to claim authority here. I'm frankly baffled that anyone, today, would try to claim authorial intent as a thing.
Again, it's a total cop out is the primary reason I reject it. "Oh, I didn't mean that." is the mating cry of the Internet Troll, not someone who actually wants to be taken seriously.
