I’m not convinced academia purged itself, at least not in any way that they should be ashamed of. Reality has a liberal bias, and my extremely conservative uncle at one point mentioned how he didn’t want his kids to go to college, because college turns kids atheist. Actually, learning things opens your mind, and so the standard conservative positions come off looking pretty stupid after critical examination, so conservativism (i.e. dogmatism) and learning are inherently at odds. Falsifying or omitting things just to suit the feelings of conservatives is wrong, even if the alternative is to “purge them” from academia by making their stupidity unwelcome.

Do you have any idea how smug this sounds to about half the people that need to pay for the scientific funding? I'm not a Republican, but even I'm turned off by this sort of attitude.
