I don't see where you get "impose" from. What they've done is persuade the people of these locales to alter their curriculum. They haven't "imposed" against the public will, or, in cases where they might have, the people have relieved them of their duties, as one would expect in a self-governing system.
If you're seriously drawing a connection between teaching ID and stoning recalcitrant children, I'm just not seeing it. I think any normal person in this country can immediately tell the difference, and is not about to tolerate the latter. And the fact that groups like DI have managed to pursuade some school districts to adopt some form of ID curriculum does not mean that they're controlling the school districts or are even close to doing so.
We went through the entire 19th century, which was often quite steeped in heavy-handed religious attitudes (moreso than much of the 18th century), and when there was absolutely no federal-court censorship of what was taught in public schools, without reverting to the kind of barbarism you describe. What makes you think it's going to happen now, especially with trends pointing so much the other way?
The 'public will' is insufficient to override the Bill of Rights. We are a constitutional republic, not a democracy. They imposed their religious agenda on those who teach biology, and on those who send their kids to public school in the district and don't subscribe to the fundamentalists' religion.
The rest is simply repetition; I see no purpose in repeating our positions, again. You don't see a connection between ID and a wider agenda. I do. No doubt you see me as paranoid; I see you as disingenuous.
