"Intelligent Design and AIDS Denialism: What do they have in common?
I am aware that this is an ad populum argument. What I propose is not the BEST option, but it is a better option than treating two sides of an issue as equally valid, just because there are lab coats on either side.
Even in science there are fringe elements. Knowing what is real and what is unsupported by evidence is a daunting task, but when 99.95% of scientists hold that the evidence supports one theory over another, it's a safe bet for the layman that the minor viewpoint hasn't met the burden of proof.
If you are motivated, read the papers either side have published in peer reviewed journals. That's the best solution by far."
