Dang, this is a good video, succinct and to the point.
Why are there so few conservatives in academia? Because the the things conservatives want to argue about are no longer debatable. You can’t seriously operate as a biologist, for instance, and think the Earth is less than 10,000 years old…much less put together a class within the curriculum that tries to teach that nonsensical idea. I’m not as familiar with other disciplines, but are there economics professors who aren’t fringe cranks who teach trickle-down economics, Laffer curve and all that, when the evidence makes it patently clear that it just doesn’t work?
Don’t get me wrong, I know professors who are more conservative than I am — very few of us actually go so far as to suggest that the proletariat must rise up and seize the means of production — but we do tend to exclude the extremist positions. The problem is that modern conservatism consists entirely of extremist madness. Your typical professor is not some wild-eyed radical, but a cautious, moderate advocate for incremental improvement of society, and just that level of tepid support for betterment is antithetical to conservative thought.
