Denying my personal experience and calling it ignorance is pretty fucking arrogant of you.
You're making quite a lot of assumptions about my experience, none of which is really correct. I wasn't openly hostile to these "antebellum plantation families", but I avoided them as much as possible. Most of my friends were from other liberal-leaning families.
Many of the people I spent time with were poor whites. I wasn't ever beat up by a poor white kid, and I wasn't afraid of any black kids. If I consider the political leanings of the white kids I knew, I didn't notice much difference in prejudice based on social class. So again, denying my experience just because you're mad (I assume?) that your segment of society is being painted with a certain brush. And imagining all sorts of things about my life to dismiss my attitude to boot.
Is what I wrote earlier unfair to you? Yes, probably (so are your replies to me). But I'm not talking about you. I'm talking about what I experienced, and that crosses boundaries of social class, despite your implication that it doesn't.
Prior experience over many iterations of this conversation strongly suggests your next play will be to accuse me of being (in some combination) fascist, racist, a Trump voter, homophobic, morbidly obese, or whatever other such libels occur to you. To my considerable surprise, predicting such deviations aloud lately seems not much to reduce the odds of their occurring. Let's see what happens this time!
Also, I feel no shame for being called a "rich white liberal," which really shows how little you understand my psychology (or me, period).
All this vitriol even after I singled out rich southerners in my OP. Something isn't adding up here, but unlike you, I'm not going to assume what it is. Have a good one.
(My hometown, actually, I bet. Oxford, right? Biggest net exporter of nonmalodorous feces in the state, bar none. The university draws 'em like flies on...well, never mind. Bet you never put a finger in a bullet hole on the Lyceum's frontage, the way I did.)
Where my other interlocutor and I really differ is that they expect to get a pass for having been "one of the good ones," and I issue no such passes. It isn't that I consider anyone who grew up that rich beneath my consideration, only that I'm less inclined to be patient and gentle with those who can afford about as much such treatment as they like and yet still expect it free of charge from me.
I don't even care they won't listen to me trying to explain how they're blinkered, because I have been trying for three mortal decades and that literally never works; to somebody like this one, I'll never be anything but poor white trash, no matter just how cleverly they always think they say it.
I grew up poor and white in Mississippi and I didn't grow up hearing slurs. That is white trash behavior - white trash, not poor! - as I was raised to believe from before I myself could speak. Like public drunkenness or indecent exposure, that is, an "unforced error" invariably both culpable and shameful. And here we have this fool who not only did grow up with those who knew no better, they themself is ignorant enough not to know they should have known better, yet believes themself qualified not merely to opine but to condescend. Must I wipe their nose for them as well? Another orifice, perhaps?
