I laughed at the recent South Park episode where some old guys are talking about the new wave of political correctness: "Yup... the last time this happened it lasted about 6 years"
The room for broad interpretation and the administrative issues with this particular law have never been resolved, so we've been seeing the same complaints emerge over different applications over very many years.
"The more things stay the same" doesn't have quite the same ring to it, though :)
Oh my! The more things change the more they stay the same.
