I don't agree with you.
I think it is a minority that wants Evolutionary Theory replaced with religious fables.
Right now this troublesome minority is able to do great harm.
You have expressed your fears.
I don't fear the majority.
Is a legitimate concern the same as a fear?
There are two general approaches to power - an optimistic one and a pessimistic one. The optimistic one says "It's good that this person or group has power because they can do so much good". The pessimistic one says "It is bad that this person or group has power because they could do so much harm. This even applies to situations where the power is that of self-determination: Is it good or bad when people are allowed to make their own choices as to what to eat, or whether to take drugs.
Pessimists, like me, are wary of all situations where power could be used to cause harm (albeit less concerned in the cases of self-determination where the harm is only or mainly to oneself). And it doesn't really matter if it is the majority exerting that power or a minority.
Is the principle that all schools should teach a curriculum laid down by government a good one? If you believe that the government will, and always will, act in what you think are the best interests of the people, then you will probably think it a good idea. If you are worried that this government, or some future one, will not do that - either because they want to act in the best interests of some faction or because their ideas of what the best interests of the people are is severely misguided - then you might legitimately be very concerned about giving them that power.
The majority has never had real control anywhere.
How could it possibly do worse than control by the minority?
While it is true that things can always get better, it is also true that things can always be worse. And in general, there is much greater scope to make things worse than there is to make things better. I'm not sure the majority are particularly good at differentiating between changes that will make things better, and the far greater number of changes that would make things worse. Of course it is also true that a random minority will not be particularly good at it.
