Thanks, Frank! The problem is that, at some point, a certain group of sociologists got together and decided that "institutional racism" and "systemic racism" should be shortened just to "racism" (apparently, 3-5 extra syllables are just too inconvenient for them to utter), for ease of reference, when discussing power imbalances based on race. As a result, they coined "prejudice" and "bigotry" as alternative descriptors for when White people (and even some other POC) experience racism in the social and cultural realms.
That basic concept of theirs has now spread like wildfire through academia and penetrated mainstream culture. Now, obviously, there are still multiple millions of people out there who view subcategories of racism in the more reasonable way that I delineated. But they are being shamed into silence by DiAngelo's cult and its sympathizers. What's even more ironic is that not all Critical Race Theory academics necessarily have the same definition of "racism," as Ibram Kendi's differs slightly from Robin DiAngelo's (as one example). But the common takeaway that these cultists seem to be peddling is that using semantics to "bash whitey" is the recipe du jour for achieving "wokeness" and equality/equity.
