Is there any evidence that non-scientists can convey the concepts better? I think creationists aim to obfuscate... and it's hard for anyone to fix... scientist or not. I think a lot of people think they know the way to inform even though they have problems conveying the basics of evolution themselves. I think you are one of those people who think you understand evolution, but cannot convey the simplicity of natural selection because you have a vested interest in describing the entire process of evolution as random.
Scientists, at least, know why that doesn't work... why that is part of the wedge strategy... and the best definitions for avoiding the most common straw man. Still, I've never seen a creationist male over 40 change his mind the slightest on the issue, and I'm not sure they can. I've seen young people and women of all ages able to learn the basics so long as they get a basic grasp on natural selection... even people who were creationists in the past. Such people as Michael Shermer and Newlyfound (on this forum) credit Dawkins' for their understanding. I think if anyone can convey the concept to others-- he is the best by far. But he has written extensively... and there is information all over the web. Facts aren't debatable. And anyone curious enough to know the facts has much information readily accessible in every Natural History museum, biology text, Talk Origins, Dawkins' writings, etc.
Creationists think they know things they do not know and their goal is to obfuscate understanding. And those critiquing scientists as being poor spokespeople are often very poor spokespeople themselves. Dawkins has won an award for conveying the understanding of science to the public. I'm not sure any critics of scientists have.
