Absolutely nothing.
Unintended consequences area a bitch.
I always marvelled, in the 60s and 70s, at the trend which glorified ignorance and even invented "multiculturalism" as something good.
Never in my worst nightmares did I ever imagine that doublespeak would become the norm, and that it would seriously be discussed in news analyses, and talked about as anything other than a joke.
And people wonder why I wish to go live in another country.
