I read Blood and Iron by Katja Hoyer before I started Weimar, which is a very brief beginner friendly account of the years before the first world war and the Weimar republic. It's a good introduction to set the stage for the ultimately failed first German republic.
The Weimar book is much more thorough, going into a lot more detail and nuance, which I feel is worth it for one of the most interesting and defining times in modern history. Definitely worth a read, though I'm not sure if it's been translated to English.
It's quite optimistic to think people would read even that, but imo it's not an issue of understanding. In my experience, people pick a side and stick with it. Most people cannot be convinced of anything.
