I put "controversial" in quotes for a reason. Many of the topics that are supposedly controversial are not really contentious at all among people who are properly informed and rely on a scientific understanding of the physical world around us. However, due to the fact that scientific literacy is sadly lacking on this great planet of ours, "controversy" emerges when individuals, groups, societies, and nations are forced to confront their nonscientific worldviews with the findings of science. Of course, skepticism is a healthy and powerful thing. But skepticism in the face of overwhelming evidence is not healthy, so long as you remember what the word "overwhelming" means. And facts themselves are not controversial. 

Through the years I have received countless e-mails and have read hundreds of article comments imploring Ars to keep "political" stuff off the site. Such entreaties most commonly occur in relation to our scientific coverage of climate change or evolution, but also when we cover biological and anthropological matters of gender and sex. (They also come to a lesser extent when we cover the inherently political world of intellectual property, where, coincidentally, there are far fewer facts—but that's outside the scope of this editorial.)
