First, progressives will never achieve their goals as long as they are hostile toward and ignorant about the faith of 100 million of their own people who are born again Christians.
Second (and we know how difficult this is to believe) there is an incredibly large and beautiful social movement exploding among evangelicals right now that stands for nearly all of the same causes and goals that secular progressives do. Those goals include: eliminating poverty, saving the environment, promoting justice and equality along racial, gender and class lines and for immigrants--and even separation of church and state.
By learning to work together with "progressive" evangelicals, secular progressives will stand a better chance of achieving their goals and also learn an enormous amount from these remarkable people and their organizations that will help secular progressives strengthen their own movement.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
