I think a lot has to do with how one views them.
For instance I think most people (even atheists) would accept that a harmonious world view consists of a symbiotic mix of belief and reason.
Allright.
eg - One may have a belief that a certain woman is their mother, and this is a reasonable idea since it is compatible with one's experience (I don't think even Dawkins had a dna test done on his mother)
Not that DNA tests are 100% proof. There is always the possibility of human error, of the samples being contaminated, of other possible factors that can interfere with the outcome of a test.
So even with a DNA test, it all comes down to
trusting it ... which brings me to the next point -
I guess the devil of the details (at least on sci) lies in extending it to the metaphysical - IOW making claims about the ultimate nature of reality and the degree this does/does not require the contribution of reason/faith as the most important (as opposed to one and only) player.
So the underlying issue seems to be about that which is taken for granted and thus ignored; that which is exposed and declared; and that which is unknown.
Which also brings in issues of self-image and self-presentation, e.g. 'I want to appear powerful to these people, therefore I will use power words such as 'truth', 'reality', 'proof' in a positive manner and so that I will appear on the winning end.'
I think our Western culture is one where approval from many people can be gained by exhuding confidence, and one of the ways to do that is to use power words and power formulations, borrowed from science and applied as absolutes, or borrowed from spirituality / religion / philosophy and applied to science; whether they are accurate or not is another matter. Many people are not intelligent and educated enough to tell the difference, or they are too distracted or intoxicated to do. So the power words approach works.
I apologize for the speculative tirade. I am just trying to understand the appeal and power of someone like Dawkins - as my first reaction is to succomb to him.
