Absolutely i agree you're right to. But actually now i think it's quite a good piece - for satire (to be honest i'm not very clear on what that means which is why i didn't describe it as such) to be effective at changing people's minds, rather than just preaching to the converted in an inside joke kind of way, it has to be not that obvious. Ideally a realisation should dawn on the reader it's aimed at, perhaps sometime later.
Of course it doesn't have a very high success rate, but i think if/when it does, it's probably a lot more effective than being disagreed with in a straightforward manner.
I suppose there needs to be a campaign of various amounts of being-hit-over-the-head-with-it and in a wide variety of places...
