One who insists that -- or behaves as if -- science is a "belief system" (rather than a system of evidence gathering and analysis) is truly "anti-science". And one who insists that scientific fact is the product of human "consensus" is a particularly stupid or duplicitous antiscientist.

I would that persons doing politics under the color of science, e.g. anthropogenic global warming, and persons proselytizing under the color of science, e.g. Dawkins, were not included in the group we call "scientists."
