The purpose of Newspeak was not only to provide a medium of expression for the world-view and mental habits proper to the devotees of IngSoc [English Socialism], but to make all other modes of thought impossible. It was intended that when Newspeak had been adopted once and for all and Oldspeak forgotten , a heretical thought — that is, a thought diverging from the principles of IngSoc — should be literally unthinkable, at least so far as thought is dependent on words. - George Orwell, afterword to the 1949 edition
Yep. Modern “political correctness” and hate-speech laws closely mirror Orwell’s Newspeak.
