"But that's okay, because according to Tom Brevoort, Spider-Man has nothing to do with responsibility."
Er, no, he said that's it's not the central theme of the series. I'm not sure I agree with that, but it's a far cry from the series having nothing to do with responsibility. I don't think Action Comics as a general rule is about the Bottle City of Kandor (current arc notwithstanding), but that doesn't mean I think Superman has nothing to do with Kandor.
Knowing you, you'll probably say that even if that's what he means, it still shows a fundamental misunderstanding of the character, or something along that line. Which is all fine and dandy an opinion for you to have, but it doesn't make your original claim about what Brevoort said any less in error.
