An extremely high percentage of professors disagree with conservative principles. Professors' common value system typically includes atheism, censorship, socialism, unjustified claims of expertise and knowledge (for example, the dogmatic promotion of the theory of evolution), liberаl beliefs, liberal grading, liberal bias, They are also accused of anti-patriotism, lack of productivity, bullying or discouraging conservative students (for example, homeschoolers), and promotion of sexual immorality. In a Zogby poll, 58% of Americans said that the bias of professors is a serious problem, while 39% said it is a "very serious" problem. The survey demonstrated further that "an overwhelming majority also believe that job security for college professors leaves them less motivated to do a good job than those professors who do not enjoy a tenured status - 65% said they believe non-tenured professors are more motivated to do a good job in the classroom." One study in 2008 found that "Texas university professors overwhelmingly favor Democratic candidates in their campaign contributions."
Professors block the granting of a tenured professorship to anyone who:
- criticizes the theory of evolution
- criticizes feminism and/or abortion
- opposes the homosexual agenda
Politicians, especially liberal ones, are routinely given high-ranking academic positions. Examples include:
Crimes by Professors
- At Northern Kentucky University, language and literature professor Sally Jacobsen incited some of her students to vandalize a pro-life display by Northern Right to Life, the campus pro-life group. Jacobsen herself also participated in the vandalism, which involved destroying rows of white crosses symbolizing the graves of aborted children. Jacobsen justified the vandalism as free speech, stating, "I did, outside of class during the break, invite students to express their freedom-of-speech rights to destroy the display if they wished to." Jacobsen was unrepentant until given the choice of facing criminal charges of theft, criminal mischief and criminal solicitation or apologizing. Jacobsen chose the latter and also paid Northern Right to Life for damage to the display. Jacobsen was suspended by the university and subsequently retired.
