I guess the fashion world still has to deal with actual people who still speak English, rather than Newspeak. In the fever-swamps of academe where English has been replaced with a real-world analogue of Newspeak in which words like "racist", "fascist", and "health care" (to choose the most prominent examples) denote whatever the left wants them to mean in any given context (but with the first two always having a strong negative connotation, the last having a positive connotation, whatever they are being used to refer to), the assertion "all whites are racist" is a truism since one of the Newspeak meanings for "racist" is "white person".
