I have banged on here at NRO about the corroding dishonesty of the Intelligent Design project, arguing that it arises from the very nature of the thing: pretending, in hopes of winning the occasional church/state lawsuit, to be one thing (a pure-science research institute), while in fact being a different thing (a Christian-proselytizing lecture agency, pressure group, and publisher). There is nothing wrong with being either of those things: the corruption stems from being the one while pretending to be the other. Not only is this dishonest in itself, it does no good to either cause.
Charles Johnson over at Little Green Footballs has been doing a few rounds with the Discovery Institute, in which the DI sleaze tactics come through loud and clear. It makes for entertaining reading. Plenty of links to follow.
