My reddit activity over the last 6 months since I joined has been primarily focused in r/atheism, a community I greatly enjoy (though I am now happily exploring other subreddits as well). My rather thoughtful secret santa sent me two books that I've eyed up in the past but never purchased:

"Godless" by Dan Barker -- "How an Evangelical Preacher Became One of America's Leading Atheists", and "The Portable Atheist" [edited] by Christopher Hitchens

So excited! Thank you!
