Sounds like the old flap (about 30 years ago?) about Franz Josef Strauss of Bavaria, there was a rock band which wrote a song about him with lyrics something like "Franz Josef, the pig, Franz Josef the lusting swine." When the rock band was castigated for this, they said that the lyrics referred to their mascot, a cardboard pig they had on stage or something, and that any resemblance to living pigs was purely coincidental.
The real question is why Ann Coulter is thought of as a doctrinaire conservative, given that she loves Chris Christie (gun grabber) and has dated (and therefore presumably been to bed with, considering who he is) Bill Maher.
Cheers!
Consider Mary Matalin, an alleged "key Republican strategist" during the 1980's and 90's, who served as deputy campaign manager for Bush the Elder's 1992 run.
Then in 1993 she marries James Carville, who she'd presumably been dating while working on Bush's campaign.
I remember lots of people going "WTF?", but it just illustrated one thing: Mary was performing a role. Likely, so was Carville. They don't necessarily believe their lines any more than any actor does.
The same is probably true of Ann Coulter. She has a persona (conservative firebrand) which makes money for her. Bill Maher has his own persona which makes money for him. What they truly believe in (if anything) is unknown.
