I was an outspoken atheist for years until I returned to the Church a little over two years ago. I wasn’t angry and most atheists I knew weren’t either. For a great many it’s simply a lack of belief in any deity for lack of evidence. Mostly rational people who don’t venture past materialism.
I think the biggest hurdle to get over is the idea that most theists think God is some anthropomorphic magical figure in the ether, otherwise know as a sky daddy. A benevolent bearded man in the sky, so to speak. This is the version of God that most atheists, to include Hawkins and Harris argue against, and for good reason. A lot of Christians and other theists seem to have a superficial understanding of God. Fortunately, for me anyway, the Catholic Church does not.
