Leftist Take On Hypocrisy.

The reason any conservative's failing is always major news is that it allows liberals to engage in their very favorite taunt: Hypocrisy! 
Hypocrisy is the only sin that really inflames them. Inasmuch as liberals have no morals, they can sit back and criticize other people for failing to meet the standards that liberals simply renounce. It's an intriguing strategy. By openly admitting to being philanderers, draft dodgers, liars, weasels and cowards, liberals avoid ever being hypocrites. - Ann Coulter
