It's because, ultimately, the post is about nothing more than the author being tired of hearing and seeing other people's outrage. The author notes that the world is improving but treats that as magically disconnected from anyone having problems with the status quo. Everyone is just some rando online with no effect on the world. (Why then try to write an article to change people's minds? is an open question...) And the great rhetorical weapon of today is framing what you don't like as a pathology of those you disprove of. They aren't doing what you want? They're dysfunctional or sick. They do something you dislike or value something you don't? They're infected or addicted. Etc.
