When we are threatened we stop being rational. We close our ears as if doing this saves us from the truth.
Yup, you certainly do.
Perhaps you should stop doing that.
Funny thing about "truth"; Real truths are important, but of limited scope. Religions, however, believe that there are truths that will usher in utopias - that (if only everyone could be persuaded to believe) will change humanity globally and for the better.
The easiest way to detect a religious belief masquerading as "truth", is to ask what effects it has outside its immediately obvious field of importance.
True statements about how eyes work, for example, are of use to optometrists and the designers of optical instruments. They are of interest to people who study eyes, and optics.
True statements about how eyes work are utterly unimportant to people whose interest is world peace, or an understanding of human nature, or who want people to be nicer to each other.
And the nice thing about this methodology for separating claims about specific systems, from faith claims of a religious nature, is that it works even when we don't know whether a given claim is actually true or false.
Just the scope of the claim is enough. If it's actually going to revolutionize the world, a new discovery will do so in complex and incomprehensible ways, such that the discoverer cannot predict the effects - for example, the inventors of the transistor didn't claim, and couldn't know, that their idea would utterly transform every human's daily life, and had they claimed that it would, it would have been sensible to dismiss those claims as quackery.
What they actually claimed was "hey, this might be more reliable and somewhat smaller and lighter than a vacuum tube".
If the originator of an idea predicts that it will have massive and wide-ranging effects
that he understands and can predict, then he's a religious nutter.
The actual originators of ideas that genuinely go on to have massive and wide-ranging effects are always as surprised as everyone else by their disproportionate impact.
