dichotomy is sometimes the right way to go about things,
but more often than not, an accurate epistemology built off of dichotomy is impossible because language has a way of contradicting itself when put under a magnifying glass.
Nobody really thinks completely in dichotomy, everyone thinks in a spectrum to some extent (otherwise there would be no way of solving a problems other than trial and error, unless you were able to view the problem in a spectrum of possible solutions).
There are just some people who think in a wider spectrum than others.
As far as being an “absolutist”, I don’t think that absolutists really need to think in terms of “black or white”, “right or wrong”, but instead they simply poison the well (disagree with everything that is being said just because they don’t like the person saying it or because they don’t want to be wrong) instead of admitting to being wrong. In an argument, they will keep coming up with more and more excuses to explain why they were originally right, until eventually they make an excuse that can’t be proven (such as “because God made it that way” or “no you are all wrong and it isn’t possible for you to understand why you are wrong”).
They don’t care if their claims that they made in the past end up contradicting their current claims, because for them it is all a matter of “avoid being wrong no matter what”. They are terrified of being wrong.
