And also, some speakers like Richard Dawkins tend to attract a lot of nonsensicle discussions in the Q&A after his talks, especially 10 years ago. The blinding incorrect, unsound arguments and relentless pushing for it, opened my eyes in one particular way.

If you look/listen carefully, you'll notice that Dawkins is quite skilled at accurately describing/explaining what he means, to emphasize key points, or to ridicule in order to emphasize the part that's silly, as opposed to ridiculing a person. The responses that are then misplaced, are also eye-opening.
