"Don't you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it. Every concept that can ever be needed will be expressed by exactly one word, with its meaning rigidly defined and all its subsidiary meanings rubbed out and forgotten."
That's one point that Orwell got wrong. In the real-world analogue of Newspeak, the meaning of words is destroyed by being made malleable or even fluid and able to be changed at a moment's notice (and even retrospectively) as serves the interests of the Party (read the left or the Democrats as the Party).
Take for instance, "racist": it can mean the dictionary definition, any person of (predominantly or entirely) European ancestry, a critic of any program or policy the left fancies benefits racial or ethnic minorities, an honest reporter of Islamic doctrine concerning jihad or sex slavery, or a host of other things as serves the interests of the left (but all of them are supposed to have the near-universal condemnation of the dictionary definition attached to them).
Or "health care": it can mean the services provided by physicians and allied-health professionals, health insurance, or government mandated and defined health insurance plans. Thus changing Obamacare in any way is called "taking away people's health care", making it sound like doing so would ban them from engaging the services of physicians and allied-health professionals, when in fact the changes might well make it easier for them to do so.
Orwell assumed that the corruption of language in the service of a one-party state (don't doubt that's what the Democrats really want -- oh, they'll be happy to have a rump GOP the way there are tolerated political parties besides the Communist Party in China, but they want to be the ruling Party) would proceed on the basis of reason. In the playing out of history since he wrote
1984, it turns out it works on the basis of emotion: a word with strong positive or negative associations has its meaning expanded so that that emotional reaction will attach to something else in a way that serves the Party.
