I was pleased to see that Poppagator way down South recognised the tongue in cheek side of it. It's a lively piece of rhetorical over-statement, a kind of irony.

I'd read it as a way of dispersing anger - "venting" as Jude called it there - rather than of generating it. At least that's how it should work in the kind of places where people have the ability to stand back while they are reading it. But of course the places where that ability is common are not always to be found everywhere. I'd imagine, from what I've heard, that Maine is one of the places they are good at that stuff, and that would have been why kendall directed our attention to it.
