As I posted to the Disqus thread under the original article:
Pay attention: anyone who asserts "all whites are racist" has just identified himself as a speaker of the real-world version of Newspeak, rather than of standard English. Real-world Newspeak sounds more like English than Orwell's fictional totalitarian replacement, with its neologisims like "cisgendered" and "heteronormative" not showing up in ordinary conversation the way "double-plus-ungood" would for poor Winston Smith and his compatriots. But it serves the same purpose of debasing the currency of thought so that it becomes difficult (and ultimately impossible) to think thoughts against the ideology debasing the language (that of the cultural left in the real world or the Party in 1984).
Real-world Newspeak functions by taking words or phrases and loading them with multiple meanings which shift as needed for the benefit of the left. For instance, the Newspeak "health care" can be the equivalent of the English phrases "health care", "health insurance", or "government mandated health insurance", so that proposals to abolish government mandates in health insurance can be called "taking away people's health care" and made to sound like they will bar people from emergency rooms.
In the case in point the Newspeak "racist" can mean the same the English phrases or words "person who advocates differential treatment under the law of persons on the basis of skin color or ethnicity", "caucasian", "accurate reporter of Sharia law", or a whole host of other things, all of which are supposed to share in the now nearly-universal condemnation of the first listed possible English translation.
