Another great column of the lack of ideological diversity in academia. This sums it up:

I could no longer blame the students for shying away from hot-button issues like Iraq: For them, the academy does not foster thoughtful discussion of thorny issues, but harbors the potential at any time to unleash the visceral reactions of their superiors to what students think are their own reasoned political positions. For students, the risk of speaking up is much the same as it is for me: They risk losing the respect of professors and perhaps endangering their long-term aspirations.
