You're getting rather silly with your ridicule, Mary Anne. No one is saying get rid of all the liberals (other than you). What's requested is some balance. If you're a conservative wanting to enter a graduate program in the social sciences, your chances of earning a Ph.D. are reduced unless you pass the liberal litmus test. It's the pool of Ph.D.s that make up future faculty hires, so this litmus test is self-selecting for liberal orthodoxy.

As George Will wrote recently:

A filtering process, from graduate school admissions through tenure decisions, tends to exclude conservatives from what Mark Bauerlein calls academia's "sheltered habitat." In a dazzling essay in The Chronicle of Higher Education, Bauerlein, professor of English at Emory University and director of research at the National Endowment for the Arts, notes that the "first protocol" of academic society is the "common assumption" — that, at professional gatherings, all the strangers in the room are liberals.

It is a reasonable assumption, given that in order to enter the profession, your work must be deemed, by the criteria of the prevailing culture, "relevant." Bauerlein says various academic fields now have regnant premises that embed political orientations in their very definitions of scholarship:

"Schools of education, for instance, take constructivist theories of learning as definitive, excluding realists (in matters of knowledge) on principle, while the quasi-Marxist outlook of cultural studies rules out those who espouse capitalism. If you disapprove of affirmative action, forget pursuing a degree in African-American studies. If you think that the nuclear family proves the best unit of social well-being, stay away from women's studies."

This gives rise to what Bauerlein calls the "false consensus effect," which occurs when, due to institutional provincialism, "people think that the collective opinion of their own group matches that of the larger population." There also is what Cass Sunstein, professor of political science and jurisprudence at the University of Chicago, calls "the law of group polarization." Bauerlein explains: "When like-minded people deliberate as an organized group, the general opinion shifts toward extreme versions of their common beliefs." They become tone-deaf to the way they sound to others outside their closed circle of belief.

Who would think that you'd be in favor of close-mindedness at institutions of higher learning?
