Often liberals refuse to admit that they are liberals, in the hope of appearing more reasonable. Hillary Clinton refused to admit in a presidential debate in 2007 that she is a liberal. Similarly, Michael Dukakis refused for a while to admit that he was a liberal during the 1988 presidential campaign. Only out of desperation did Dukakis admit that he was a liberal, and even then he admitted only that was a liberal like President Harry Truman, who served 40 years earlier.
Liberals like to bash President Bush as a war monger and cite President Clinton for his eight years of peace and prosperity. Liberals will deny record low unemployment, more people owning their homes and President Bush going after terrorists while protecting Americans from further attacks. Liberals will selectively forget that during Clinton's term: the Rwanda massacre occurred, the bombing of the USS Cole, the war in the Balkans, the two US embassies bombed in Africa, the Kobar tower bombing in Saudi Arabia, the Somalia conflict, the missile strike against Afghanistan and the bombing campaign against Iraq. Also, liberals will deny that Clinton's economic policy ignored a series of high profile companies that eventually collapsed due to fraud: Enron, Tyco, Worldcom and Qwest.
As part of their denial, liberals often use the word "denial" pejoratively against conservatives. Alleging that conservatives are racist and reject science, they use terms like "global warming deniers" and "climate change deniers" in an attempt to link conservative viewpoints with Holocaust denial, Nazism, conspiracy theories, and pseudoscience.
- E.g., the granting of the Nobel Prize to an understudy of Fred Hoyle to punish him.
- See, e.g., liberal adulation of Ted Kennedy despite his paucity of achievements.
- A public school student who once "tape recorded a teacher making religious remarks to his students" to complain about it then later objected to a textbook explaining how prayer is censored from public school schools by court decisions. 
- "Among those who admitted having sex, the rate was even more disturbing -- 40 percent had an STD."

- Compare  (with an explanation of why there is a big difference) with New York Times (downplaying the difference and pretending that no one knows why). The New York Times denies overwhelming evidence, including the following:
- "Female athletes, particularly basketball players, are far more likely than their male counterparts to suffer ACL [Anterior Cruciate Ligament] injuries." Stephen Hargis, "Girls have more torn ACLs," Chattanooga Times Free Press (Tennessee), D1 (Feb. 4, 2005). According to the American Academy of Orthopaedic Surgeons, the risk of women tearing their ACL is 1 in 100. This number drops significantly to only 1 in 500 for men. See Nikki Usher, "Knee injury takes toll on girls playing soccer five times more likely than males to suffer a torn ACL," Philadelphia Inquirer, A01 (Nov. 29, 2004). "Compared with guys, female athletes run an eight-times-greater risk of tearing the ACL, a fibrous band that connects the shinbone (tibia) to the thighbone (femur). Basketball, soccer and other sports that require cutting moves or jump shots can put athletes at risk." Kathleen Fackelmann, "Girls face higher knee injury risk," USA Today, 15B (Aug. 24, 2004). Timothy Hewett, PhD, the lead researcher on a definitive study at the Sports Medicine Biodynamics Center at the University of Cincinnati, says this is "close to a billion-dollar problem in girls and women in the USA. ... Even after girls have recovered from the acute injury, the changes in the joint may set the stage for osteoarthritis of the knee ...." Id. That obvious suspicion was quickly confirmed: a study subsequently published in Arthritis & Rheumatism demonstrated that "more than half of ... 103 soccer players, who were ages 14 to 28 at the time of the ACL injury, suffered osteoarthritis of the knee at the time of the study -- about 12 years later." Kathleen Fackelmann, "Girls' knee injuries have later consequences," USA Today, 9D (Oct. 7, 2004). "Many of the women, who were about 31 by that time, also said they had pain or some other disability that made it hard to conduct daily activities." Id.
