Even when I was a Christian I was a fan of Dawkins. If you read his books/watch his talks/debates he always comes across as very reasonable and polite. Way more so than you might have been lead to understand. The worse he has ever gotten was with the name of that documentary, "Root of all Evil", though he didn't pick the name and in fact disliked it, noting that it was a bad title because it wasn't true (religion is not the root of all evil).
