@fresco,
My position remains the same. The interests and needs of the local community are more important than the shared values of the nation.
The most interesting case is the first one you raised-- a community of "fundamentalist" Christians in a secular society. This kids have some needs that are distinctly different than kids from a largely non-religious society-- specifically (unless you think that a goal of education is to change a kids religion/culture) you are going to need to give these kids the ability to live as religious citizens in a secular society.
First... you still haven't given me a case where working with local parents and community members is a bad thing. Working with means first listening, then discussing any controversial issues. This discussion should be a dialog, with the understanding that everyone the kids best interests in mind.
The case of evolution is the the obvious example. When I was studying for my education degree-- I had the interesting experience of visiting the Navajo reservation in Arizona. The community leaders in this case were concerned that "Anglo" culture had already drowned out their own culture so much... and now even science educators were imposing more values to replace tradition cultural ideas about creation.
In this case, it seems to me that a teacher who came in with a curriculum already set up-- deaf to the concerns of the parents, would be both irresponsible and ineffective. A teacher who comes in with the message that their parents are ignorant and backwards isn't doing any benefit to kids.
What is wrong in these cases with sitting down with parents and community leaders to come up with lesson plans that met both the need for the importance our country places on secular science while being sensitive to local culture and values?
I am advocating for open dialog.
The solution in many of these cases is for science teachers to teach the science with sensitivity. The kids need to understand the processes and arguments for evolution, no one demands that they reject their parents beliefs or their local culture. There are many great teachers who do just that.
The key for an educator is respect for the community you are serving, and the willingness to listen to and hold respectful discussions with the parents and community leaders.
It is a very bad thing for educators to be in conflict with the other institutions responsible for bringing up children in the community.
