The credibility of dissenters has nothing to do with the size of their group, especially in matters of science. If there is one heretic among 20,000 in the orthodoxy, and that heretic has better evidence, then the heretic is more credible. Not that I doubt the confidence of a 20,000 strong wall of scientists, but I won't discount the credibility of dissenters just because there are fewer of them. That's intellectually dishonest.
