There is a polarity here between truth and error. Evolution is true and anti-evolution views are wrong. But where the real room for debate emerges is when scientists and philosophers develop metaphysical claims on the basis of physical facts. For example Social Darwinism was the most extreme example, using survival of the fittest to justify laissez faire capitalism. In that case, evolution is used politically by analogy to support values that are not themselves evidence based.
Dawkins’ alarm is about the 40% of Americans who have consistently told polls they believe the universe was created in the last ten thousand years by God. It is morally essential to expose anyone who would give comfort to this evil delusion. Believing in the alienated fantasy of YEC opens the path to support for climate denial, nuclear war, indifference to ecology and science and various other apocalyptic dangers that threaten to cause human extinction. The situation is highly polarised, and being polite about it is like refusing to tell the coal miners that their canary has just died.
I personally think of the debate between scientists and creationists in terms of the apocalyptic vision in Revelation 12:7-13 of the
war in heaven between Satan and the Archangel Michael, with the creationists representing Satan against the scientists who are on the side of God. As God implicitly
says at Revelation 11:18, his wrath is against those who seek to destroy the earth. That means creationists.

Faith is entirely about stories that give us meaning and direction. For example the Christian faith is expressed in the creeds of the church. The Nicene Creed
https://www.ccel.org/creeds/nicene.creed.html expresses belief in the second coming of Jesus Christ as the basis of an endless kingdom, as a framework for hope. It is about explaining why the world is bad and how to fix it. (Amazingly that linked version has a shocking typo regarding the Catholic Church).
When Jesus Christ is asked what is most important in life, he says love of God and neighbour. So faith is meant to provide meaning and purpose through the centrality of love.

Does the universe exist in reality? Why not unreality? What are you saying here?
This point about the meaning of ‘real’ is a useful example to show that atheist materialist philosophy cannot really do without metaphysics, despite the efforts of creationists to monopolize discussion of everything that is not directly scientific.
It is a simple logical point going back to the foundation of philosophy with
Parmenides of Elea who held that “the way of truth" discusses that which is real and contrasts with "the way of opinion," which is illusory. “Under the "way of truth," Parmenides stated that there are two ways of inquiry: that it is, on the one side, and that it is not on the other side. He said that the latter argument is never feasible because nothing can not be: "For never shall this prevail, that things that are not are.”"
So if we wish to have a coherent logical discussion about truth, we have to assume the universe is real. In answer to your question ‘why not unreality?’, that would be to accept the nihilist possibility that everything we know is false. While logically coherent, this acceptance that unreality may be true is in conflict with the common faith that the universe is real.

That the universe certainly exists? It can be argued that this is analytic, and we can be certain of it. The connotations of 'universe' and 'existence' overlap, referring to precisely the same thing.
No, the claim is synthetic as soon as we assert the universe actually has any properties such as containing space, time, matter, energy and causality. The term ‘universe’ means ‘physical universe as observed by science’. Our assumption that the universe actually exists is based on faith in the reliability of our senses in view of consistency of data.

At the root of our knowledge is a necessary trust in our senses. This simple trust is altogether different than the sort of faith we would have in a proposition. If we accept assumptions and axioms to function, they are not held with certainty. They are (or at least should be) correctly seen as provisional. We should never turn a blind eye to the weak areas of our worldviews.
Yes, it is always possible that faith could be shattered. But it is a great tragedy that
Paul Simon says he doesn’t know a dream that’s not been shattered, in one of my favourite songs.
I am exploring the psychology of the provisional. When a sense of provisionality acquires too strong a status, it can create a climate of suspicion and mistrust, paralysing the ability to act. Since Popper, philosophers of science have seen provisionality as a key ethical value for a proper liberal skepticism. To a large extent I believe this was in reaction against the mad messianic certainty of Adolph Hitler, who piped the German people into a mountain like in the story of the children of Hamlin, through beguiling insane faith in dreams of racial hatred. Hitler is the great cautionary tale of the danger of certainty, poisoning the well for certainty, and I suggest leading those who should be certain to vacate this ethical field for those whose certainty is demonstrably misplaced.
Yeats put it well a hundred years ago when he wrote that the best lack all conviction, while the worst are full of passionate intensity.

I think I see why you believe faith to be a virtue. Because it legitimizes the leap from confidence to certainty with regards to some claims. Corroboration beyond a certain magnitude is worthy of faith on top of reason, so we can have absolute certainty in the truth of the proposition. I disagree with it, but I can respect it. I think the need for absolute certainty is psychological. It's a form of closure, allowing us cognitively to move on to other problems.

Philosophically, the problem of certainty is the question of whether what are termed ‘synthetic a priori propositions’ are possible. Kant, who I greatly admire, found in this claim the basis of his whole philosophy, resting on faith that space, time, matter and causation are real and necessary conditions of all experience.
This synthetic faith, putting things together by reason to provide systematic foundations for thought, was the only basis for Kant to refute David Hume’s observation that there is no necessary connection between a cause and an effect. This rather obscure piece of logic extended for Kant into a basis for arguing why doing duty is morally good.
The problem is that duty, what Kant called the moral law within, always seems to come back to the circular argument that we should do our duty because it is our duty. Accepting that faith is morally necessary seems to be the only way to resolve this problem of the logical foundation of ethics.
In terms of why people don’t believe in evolution, the situation is that the philosophy of science never really went through its Kantian Copernican Revolution, but remains with David Hume in a nihilist scepticism, unsure of anything, paralysed by doubt. So ordinary people compare the new atheist intellectual smugness with the simple engagement of Christian evangelists, and too often find the evangelical message more comforting and believable.
