Arendt is a vice of mine, where if I could be considered ideological, it would be the logic of her ideas that I have iterated as a framework for interpreting political experiences. When you challenge at the level she did, you make very powerful enemies. What people really go after her for was not
Origins but her assessment of Eichmann at his trial, where by recognizing him as merely contemptible, she simultaneously deprived Israel of a super anti-human monster as an easy foil (edit: to have overcome something huge and evil) for their founding story, and made us each individually responsible for moral complicity in evil, and I think many people (mainly secular, I suspect) treated it as an unforgivable betrayal. They found allies among the marxists in academia she had burned pretty hard with
Origins, and her work has been pushed into the backwaters of contrarianism since.
Over the last couple of decades, there have been a few posthumous hit pieces on her, mainly by post-marxists who are among the architects of our current wave of the totalitarian strategy, and whenever I read attacks on Arendt I always ask, "why, what are you planning?"
Perfect? No. But between Arendt and Solzhenitsyn, however this wave today plays out, we can't say we weren't warned.
