so, your parents came over here with a good education, got a swank job and raised you in a middle class suburb. you studied hard and went to a good school, where you learned about white people in a sociology class.
but, how many white people do you actually know, though?
have ever gone out to where they live and talked to them? listened to their music? hung out with them?
the critical race theory is useful in a very narrow context: it describes the relationship behind powerful landowners and slaves in the southern us, and the contemporary consequences of that historical system. it's about the legacy of slavery in a very limited geographical area.
the error you make when you take that very narrow theory and try to apply it the broader world around you is called generalizing the specific and is endemic in the social sciences.
and, it really fails the most basic empirical tests. but, if all you know about white people is what you've learned in a classroom - if you have no real direct experience with them - then you can't see how absurd the whole thing really is.
so, go out to a trailer park or a subsidized housing unit some time. spend an afternoon with some white people in the wild. see what they're really like.
