Not that they aren't correct here, but the "let me put a list of wrong opinions I disagree with that people could hold and get mad about it" theme never felt mentally healthy to me. I catch myself doing this all the time however.
The author critiques the cliches, misinformation, wrong ideas, and romantization journalists use when writing about Africa.
These are not merely some "opinions they disagree with", these are wrong and lazy writing, and it's a bad public service (they are getting millions of people the wrong ideas about a place). It surely deserves to be critiqued.
What makes me feel weird about the style however is there aren't any example of this, so if a reader does not know the field well of the common tropes, it feels like the author is just throwing together opinions people could possess (let's say opinions on how to write an Article about Africa), and then promote anger over how such people could exist.
Declaring mental illness in the face of exposed bigotry is a classic tactic, meant to discredit legitimate and reasoned grievance.
I would ask you to rethink your agreement, for your own sake.
