What do people need to know about the atheist movement?

Book #2 is basically done, but I’m going to try to write a better introduction and one thing that might be really helpful to people is explaining what’s happened with the atheist movement in the last 10 or so years. I’ve realized that I definitely don’t want to give the (false) impression that it’s all about the Four Horsemen or whatever. So what do I tell people?

Note that I’m strongly leaning towards calling the book Atheism Wins, so suggestions that fit well with that theme are especially appreciated!
