It just so happens I have — another — piece on precisely this point in the latest issue, from a reader:

Subject “Neocon” Now Has No Meaning Part 3,717,206
You’re often noted that “neoconservative” has a very hazy definition.
Indeed to some people it’s become what Orwell said of Fascism just
another word for “bad’.
The reductio ad absurdum of this came in my women’s studies class
(don’t judge!) where the professor put up this definition:
“Neo-Conservative: racist and misogynist stereotypes but in new forms”
She then asked if anyone could give any examples of
“Neo-Conservative”. A girl’s hand shot up and gave the example of
kids in the playground using the word “gay” to mean “stupid”.
(My university’s really not that crazy, I’ve had two ex-military
profs, a prof that had NRO bookmarked on their laptop etc.)
