The reactions to the essay are way more interesting than the essay itself: when "liberals" read it, they immediately get that it's about Donald Trump. But when Trump supporters read it, almost all of them go "yeah good points, but why did you write about Hitler?".

Are we doomed?

It could be that they just don't follow the news as much

Most of the Trump supporters I showed it to were well-educated and from what I could tell were very much in touch with what is going on in the world. I feel like they just don't want to "see".
