Obscurantist:
If you describe something as obscurantist, you mean that it is deliberately vague and difficult to understand, so that it prevents people from finding out the truth about it.
I think that a lot of poetry published today is obscurantist nonsense. [Collins Dictionary]
Ah. Noted in “The battle for George Orwell’s soul,” Ed West, The Wrong Side of History:
For Lynskey, Trump and Trumpism is the obvious analogy. The American Caesar meets most criteria of Orwell’s definition of fascism: ‘something cruel, unscrupulous, arrogant, obscurantist, anti-liberal and anti-working-class… almost any English person would accept “bully” as a synonym for “Fascist”.’
A neat little article.
