Ann apparently has a problem with the Post, but I don't. Every paper - - including the Washington Times and the Wall Street Journal - - has its share of humorless scumbag liberals on board. The Post is generally pretty conservative, at least editorially. I figure there's a few humorless scumbags at the Post that Ann let get under her skin. Fortunately for her, (I am pretty sure) there are a whole lot more people who read her columns than read the Post, so she will always have the upper hand in any battles with them.
Ann Coulter gives the Left some of what has been its stock in trade for 40 years. In-your-face, demonizing name calling. In their case it is quite accurate, and they don't like it. This is why they attempt to physically intimidate her- which doesn't work. O'Reilly thinks civility works best, but I disagree. The problem with "conservatives" in this country is they too often go along for the sake of getting along, turning into Lindsay Graham.
