"1... Rand's view was that in a free captialist society, money is the measure of progress and recognition, so superior people tend to become rich. Rand had contempt for the idle rich living off of inherited money."
Translation: Rand would favor strong estate taxes. (Uh oh.)
"2 ...A political Party run by Rand would not even tolerate let alone cater to the Christian Right."
Who says the Republicans cater to the Christian Right? They use it to win elections, promising they're on their side, without ever really delivering. Was abortion done away with? Prayer put back in schools? The Republicans lost 2006 in part because the Christian Right stayed home in a lot of places. (The Democrats do the same with the Progressive Left, at their peril...)
"3 ...It's become fashionable to diss Rand's writing."
It was ALWAYS fashionable to dis Rand's writing, because it is terrible by any literary standard. Her philosophy, on the other hand, is subject to debate. In the end, though, I suspect this point is just more of that good, ol' fashioned pathological right-wing self-vicitimization
"4 ... Rand may have had "followers," but Objectivism is not and never has been a cult."
I think it would depend on whether Rand bilked her worshippers of large amounts of money. Maybe the biographies mention whether this was the case.
"5...Wasn't this supposed to be a book review?"
It was: Mr. Hari writes early on,"... the books work best, for me, on a level I didn't expect. They are thrilling psychological portraits of a horribly damaged woman who deserves the one thing she spent her life raging against: compassion"
Sounds like an endorsement. Mr. Hari then focused on the question that framed the books and accounts for their appearance on the market now of all times: What is it in us that makes so many of us buy her books? These authors tried to find it by exploring Rand's life, and Mr. Hari in his review describes their result.
"6.. it's OK to be as radical as one wants to the left, but not the other way"
Two things here: First, this cliché is another example of right-wing victimization culture.
Second, and more important: You're making a crucial fallacy--- assuming that criticism of one person entails support for their adversaries. This is commonly made by people who cannot understand the concept of objective criticism, Here's why it's fallacious: Since this is a review of biographies Ayn Rand, who was not a left-wing radical, it's unclear why anyone would bring up left-wing radicals, unless they were directly influential on her life. Those that were: Lenin and the Communists. Of course, Mr. Hari does mention them and not in a positive light... so I guess even in the context of this review your supposition is false as well as fallacious. If you want a Slate biography reviewer to talk about left-wing radicals, write a biography of one. Start with Che Guevara: He was as egotistical, sociopathic, and passionate as Rand was.
