Do you think any secular group has the "right" to teach their beliefs in public school? Which ones, and based upon what criteria?
It's not possible to create and present a values-free education. Which set of values do you advocate be taught in the public schools?
There's only one reasonable conclusion one can make with respect to "public" schools. It's always a bit of a kick watching the contortions some people on both sides of this issue put themselves through avoiding that conclusion (assuming there are only two sides).
Good question. Do Malthusians have the "right" to have their population ideology taught as fact in public school? The state is presently enforcing that "right".
Anyone who wishes to be considered well educated should know the sciences of geology, biology, chemistry, astronomy and physics; all of which have findings that “cdesign proponentists” have problems with.
Do you think any science that's findings conflict with a particularly peculiar religious view should not be taught, do you think it is your “right” not to have science that conflicts with your religious beliefs taught to other people's children?
