Many people think they know what the truth is. Some of them call themselves "truthers" other comment everything they don't like with "fake news" and believe in alternative facts.
Isn't it true that everyone generates their own truth?
Those who defend the truth the loudest are actually trapped in their own filter bubble. Others know that there can only be a relative but not an absolute truth.
Suppose the Earth were a sphere.
(I know this is also doubted by the so-called "flat earthers". I am a "glob earther".)
The earth is not a perfect sphere but more like an ellipse. That's only partly true, because it has mountains and valleys - let's say dents. So you can update the relative truth more and more, but still never come to an absolute truth
I wonder, how so many people can be sure that they know the absolute truth and have to proclaim it loudly?
