I've occasionally had similar discussions - although probably not as eloquently as Dawkins - with people who think that evolution is just some big conspiracy. Ultimately it all comes down to whether someone is willing to change their mind about something in the light of new information. Some people are highly inflexible in their beliefs and no amount of evidence is going to persuade them, either because they're just not interested in evidence or because changing their mind means having to reject something which they were taught by trusted individuals at an early age.
