This question-which I first saw on a website- was originally posted as a joke on a Catholic forum, but has become a serious issue apparently in the US: why are there so few conservative college professors?Opinions differ: some suggest that conservatives would rather make millions in the private sector(ie Wall Street) rather than wait for tenure in universities on a college professor's comparatively penurious salary( I was criticized for implying that conservatives were greedy philistines uninterested in classics or history).
Whatever the reason, the implicitly Democratic and liberal at that ethos of higher education has serious consequences-namely "groupthink">. As Dr King noted- injustice anywhere is a threat to justice everywhere, as little affection as conservatives are held by liberals( Teresa Wagner is currently suing the Iowa College of Law for discriminating against her based on her conservative and pro-life views in favour of a liberal colleague). News that the ROTC programme is due to return to Ivy League campuses like Yale and Harvard in the wake of the repeal of DADT; they were first ousted from academe in the wake of the Vietnam War) may see a thaw in the long estrangement between the US military and the nation's academic community.
Perhaps the best resposne would be to offer tenure on "a first come, first served" basis, irrespective of political viewpoint.
