Matt brings up two pieces of evidence: Matt Yglesias saying that lying is okay was one distressing example. Well, duh. Yglesias is a liberal and I have yet to read a liberal blogger who doesn't believe the ends justify the means. There is no true objective truth, after all. And, really, lying is fine, if a greater truth is served yada yada. This is not new. Nor is it shocking. Everything from science (Al Gore and global warming) to social science (single mothering is as good as dual-parent families) to religion (Christianists!) to media coverage is manipulated to serve the statist i.e. Democratic good. And to make the arguments, lying isn't just recommended, it's necessary.
The left and the media love to hyperventilate about the right wing “hate speech” on the Internet, but the anger and vitriol of the left dwarfs that of the right, especially where female or minority bloggers are concerned. Hateful comments are not uncommon at lefty blogs like Daily Kos. That kind of hostility forces the Huffington Post to occassionally close comments on articles involving certain topics like Israel, the military or even Margaret Thatcher.
Pictures of them are photoshopped into violent or sexually explicit positions, and they are stalked, online and occasionally offline. Liberals track down their addresses and phone numbers and leave obscene messages, even threaten rape. Moderate blogger Ann Althouse nailed the root of the hostility, “...people on the Left think you are evil if you don't agree with them, that you're actually a bad person” (all bold mine).
