So, no, we shouldn't be teaching every point of view, because that'd be stupid.
Similarly, I've flagged this article, because it's just another "ho ho ho look how superior we are to those backwards Southerners yes...."
Was that meant to be sarcastic? Because that's rather bigoted. I think that creationism is irrational, but it's a very large jump to say that a person is therefore incapable of critical thought.
If the students themselves or the parents "want" creationism to be taught, they may elect to take a religious studies program.
Also of note, anyone's inability or unwillingness to accept reality doesn't make reality any less real.
The Soviet union, incidentally, did exactly that. Here's one of the initially funny consequences of forcing scientific views on everyone, currently referred to as Lysenkoism [1]. It's only funny until you realize just how many people this affected and what was done to enforce this.
Short list of people executed as direct result of attempts to enforce scientific socialist/soviet dogma:
Isaak Agol
Solomon Levit
Grigorii Levitskii
Georgii Karpechenko
Georgii Nadson
Is scientific dogma really any better than religious dogma ? I would argue that the vast majority of Christian schools teach both creationism and evolution. What is wrong with that ?
Incidentally, like the things it's describing, there's quite a bit of evolution in evolution itself. So much, that what most people were taught as evolution is no longer considered true.
I also love the naivite in this position. As if this pushing of evolution is being done to advance scientific knowledge. It is being done for the same reason that the French revolutionaries did it (another example of people who pushed scientific dogma, another example of that practice ending in mountains of corpses). They did it for a simple reason : to make people follow the state like they follow the church.
There are other contexts in which teaching non-scientific "points of view" that people might encounter could defensibly be taught.
