TV Ontario (TVO) has a daily program called The Agenda with Steve Paikin. It's usually very good.
Last week they had a show on the atheist bus campaign featuring Justin Trottier of the Center for Inquiry and Robert Buckman, a well-known Toronto atheist. Here's the entire show. I don't think any one of the participants is particularly proud of their performance. But see below ....
At one point in the show, the Christian woman, Kathy Shaidle, brings up the "Stalin, the atheist, killed 30 million people (therefore God exists)" argument and Robert Buckman tries to answer in a reasonable manner. He doesn't do a bad job (excerpt below) but Canadian Cynic has a suggestion: What Robert Buckman should have said.
I caution Sandwalk readers that CC's language can be a bit crude ... but it sure is funny.
