After 1991, its use as a pejorative phrase became widespread amongst conservatives in the US. It became a key term encapsulating conservative concerns about the left in cultural and political debates extending beyond academia. Two articles on the topic in late 1990 in "Forbes" and "Newsweek" both used the term "thought police" in their headlines, exemplifying the tone of the new usage, but it was Dinesh D'Souza's "Illiberal Education: The Politics of Race and Sex on Campus" (1991) which "captured the press's imagination". Similar critical terminology was used by D'Souza for a range of policies in academia around victimization, supporting multiculturalism through affirmative action, sanctions against anti-minority hate speech, and revising curricula (sometimes referred to as "canon busting"). These trends were at least in part a response to multiculturalism and the rise of identity politics, with movements such as feminism, gay rights movements and ethnic minority movements. That response received funding from conservative foundations and think tanks such as the John M. Olin Foundation, which funded several books such as D'Souza's.
