I don't do match cuts really. That's a ridiculous thing to say - I do. But we always explore how we can propel a scene, and that's including dialogue, without doing match cuts. Because the audience is really willing to accept a lot of discontinuity.
The pressure to make public retractions of past statements - there's something medieval about it. What does it mean, anyway, to 'retract' what you've said? How can anyone state categorically that a thought he once had is no longer valid? In modern times an idea can be refuted, yes, but not retracted.
