I'm just a casual Bill Maher watcher. I don't watch his show very much, so a lot of the stuff in the book was new to me or I hadn't heard before. I agree with some of his points, and disagree with others, but I respect his right to say it and appreciate him for standing up for what he believes in.
If you are not a Bill Maher fan, this won't make you one. If you are familiar with his work, and you are willing to listen to some viewpoints that may not completely align with yours, this can be an interesting read. There's definitely some “back in my day” old man energy going on, so some of his points are hard to take seriously because of that. But I think he has important and necessary viewpoints on things like cancel culture, the environment, Israel, and the Democratic movement.
I recommend listening to this on audiobook since Bill Maher narrates.
