Getting tenure at a University is tough. There are a million hoops to jump through, and those hoops can be set mighty high. Even being a brilliant scientist doesn't guarantee you tenure... and certainly, promoting complete and utter antiscientific drivel doesn't help. Guillermo Gonzalez, an advocate of Intelligent Design, has been denied tenure atthe University of Iowa Iowa State. The Discovery Institute claims it's from bias.
I certainly hope so. I want to see scientific departments being biased against antiscience.
But you don't need to know my opinion of all this; it's obvious enough. So instead go read what Christopher O'Brien, Rob Knop, and Ed Brayton have to say. I imagine this will be quite the topic on science blogs for a day or two.
