As a Catholic and a chemist nut, it bugs me every time people try to wedge science vs religion. Of course, these are usually atheists who are using science as a champion against religion. Frankly, the whole thing's absurd. If you want to find a true enemy of science, there's only one place to look: politics.
While there is plenty of evidence for this (see exhibits A, B, C, D... on global warming), today we're going to look at something seemingly minor, but is so totally unnecessary and stupid that one wonders why it comes up in the first place. I give you Michigan's own Congressman John Conyers and his fight against open access of science.
