Having listened to her firsthand (if I can't find good music on long road trips I use her to stay awake), I honestly have to say her
abrasive nature is exaggerated. It's more that her callers are usually idiots who need to be kept in line lest they ramble on about
boring personal details for hours.
And she does have some useful advice, sometimes. She's also very dedicated to children, and feels parents should consider their children's interests before their own. God forbid someone tell Americans to do something other than what they want.
Of course, considering she's a converted orthodox Jew I find her moral standpoints outrageous, outdated and sometimes hateful, but I like to be honest about the reasons I don't like someone.
