Thank you for the information.
It's OK. I am actually going more or less on autopilot now, having identified and chosen the weakness in the revisionists' defense to exploit, and then using their own defensive arguments against them. It's fairly straightforward, and the main problems as I view them are not to go overboard in terms of style, presentation, and so on. For example, I've reconsidered mentioning the recent Bellesides research fraud, since I believe most ordinary people are not following that particular debate and so would be left in the dark if I were to mention that issue at this point in time. I can always save it for a future round with the diehard academics, who will certainly be able to relate to it :-).
By the way, I noticed in a recent school flyer that they solicited parent involvement in the curriculum review committee, so (after many attempts to volunteer myself, culminating in a hand-delivered letter expressing interest to the office of curriculum studies' director herself), I managed to find out when the next meeting will be, and will insert myself into their activities from here on out. Think global, act local.
Also, I note in passing another potential target of opportunity along the same lines: an old INS Citizenship manual makes the same mistake about the intent of the Second Amendment, and I would be moderately surprised if the GWB Administration has bothered to fix it. Any takers (before I get around to it) are welcome (let me know, if possible, so I don't have to duplicate the effort).
