As Voltaire didn't say*, we don't believe that creationism has any truth to it at all but we'll defend to the death your right to believe in any damn fool thing you want to. The limitation is only that whatever you do believe not cause direct harm to others. Thus nonsense about how we all got to be here is just fine, nonsense about how we treat the others with whom we share here is not, just as one example. All of which makes this complaint by Rupert Myers something we don't agree with:
Someone who is on the record as believing that the earth is flat would be an unlikely anchor of the BBC’s flagship breakfast news show. A news reporter who denied basic facts from the past such as the French revolution, the explosion of Mount Vesuvius, or the Holocaust would surely raise eyebrows at interview. Climate change denial, or a denial of heliocentrism, would be unlikely to find favour at the BBC. And yet they have just selected a creationist to front their Breakfast show.
BBC hires someone with odd views is not exactly a surprise.
A belief in creationism may be a religious belief, and we must allow generous margins to the holding of such beliefs, but creationism falls beyond the spectrum. It should be consigned to the bin of unreasonable, untenable fact-allergic nonsense. Creationists cannot be trusted to report objectively, or to interact reasonably with their interviewees and with the public.
Not so and sadly it betrays a misapprehension about how market exchanges work. It is only in a society that does not operate markets that we have to consider whether someone is wholly acceptable in the round before allowing them to perform a task. If jobs are allocated on the basis of belief then obviously what those beliefs are is of importance. But a market society operates on the basis of "what can you do for me?" That's rather the joy of it. We don't have to know whether the window cleaner supports the wrong football team, has more traditional opinions on gender roles than we might be comfortable with or is insistent that the world popped into existence last Tuesday afternoon and all memory before that is simply a general hallucination. We care only about how well they clean windows and what they charge for doing so.
The same is true of all the other interactions which make up a market economy. We don't have to worry about the sexual preferences of the provider of our morning coffee, we care only about the coffee, the price, and perhaps the smile or not with which it is delivered. It is not necessary for the car mechanic to share our views on Che Guevara, whatever those might be, we want only that she can mechanic a car for us. And so it is with the pretty faces that mumble through the scripts to us on the television. We care only for the face and the mumble, not whatever beliefs occupy the void between their ears.
And no, this is not just some trivial matter. Humanity spent some millennia where only those who held the approved ideas on matters religious were allowed to perform certain jobs. It is only in this last century or two since the Enlightenment that this has changed and yes, it really is part of that liberal and market order which has so enriched us all. It is exactly the same thing that a creationist be allowed to read the news, a Jew to own land, an atheist to publish books and us all to be free to truck and barter across the society regardless of whatever damn fool beliefs we might have about anything at all.
* The "I disapprove of what you say" line is actually from a play about Voltaire, not from the man himself.
