I am a card-carrying member of the American Civil Liberties Union and Americans United for Separation of Church and State. Robert Boston (Twitter) is the latter organization's Director of Communications, and he is the author of numerous books. His latest is Taking Liberties: Why Religious Freedom Doesn't Give You the Right to Tell Other People What to Do. I was fortunate enough to be able to attend a talk he gave in Augusta, GA, and I enjoyed his company at lunch before the talk.
