UCLA students urged to expose 'radical' professors

His motivation is clearly to get "leftist" (NB I really hate that word) teachers into trouble by circulating their names around the wingnut internet, generating thousands of complaint emails from people with nothing to do with the university, hopefully scaring the faculty and governors into firing or restricting the person concerned and intimidating anyone else. The campaign is specifically targeted at what you in the US call "left-wing" opinion, and is not tempered by any reference to context or teaching ability. It seems aimed at the sort of person who objects to being asked to read Das Kapital in a political philosophy class, or the Koran for comparative religion.
