Patterico rounds up a list of just a few Coulterisms by uttered by prominent members of the left:
The point of this list is not to argue that leftists are more hateful than conservatives. There are many documented examples of hate speech on the right; Ann Coulter provides many examples, but she is not the only one. I publish this list simply to rebut the Greenwald-spawned canard that leftist hate speech is exclusively the province of anonymous trolls on the Internet. On the contrary, prominent leftists have said some pretty awful things.
