This is an audio-only youtube video. And sadly, you may have to sit through a Mormon commercial before getting to it!
He is another former fundy who came to atheism from a close study of Christian theology. His family was deep into it and they were not pleased with his atheism, to say the least. This is the story of his coming out to his family.
If you don't already subscribe to his podcasts I recommend them. He often interviews very interesting people. This is the first one I've heard that has his own story. Afterward, some callers read the letters they've written to family.
