I'm not saying that there's people who become professors to spread their conservative ideas. Just like how there aren't really any people who become professors to spread their liberal ideas. Nobody would become, let alone remain, a professor if they used their platform to convince students of their ideology. What I'm saying is being highly educated in one area is absolutely not a guarantee you'll become a leftist, or even a liberal. And there's plenty of professors that will never share their political views, just how it should be. Some of them are certainly conservatives.
