"You may have experienced racism, prejudice or discrimination but I very much doubt you've experienced the systematic destruction of livelihood that people of color have and continue to experience."
I lived in an area where government, jobs, and schools were largely dominated and controlled by blacks. You bet I experienced systematic overt and subtle discrimination that held me back. It shocks your subset of liberals to discover this but it's a human group not race issue that merely manifests as race. If blacks are the majority, the same problems show up against any other player. Whites are majority in most areas, so the problems usually show up against non-whites. So, in mostly black areas, we get unusual expectations, more punishment more often for offenses, ganged up on, laughed away from jobs seen as appealing to blacks, served later at a food place "randomly," and so on. Same shit. Just nobody fights for us and liberals don't acknowledge it happens without... it's like a refrain... "may have experienced" prejudice/whatever in "small examples" vs (non-whites here).
Of course, you people conveniently ignore that there's different types of white people. Matter of fact, my Irish ancestors in this country and many other European immigrants would be very confused at your assessment given they got lots of discrimination. Still do if 1st generation. I like citing anti-Irish articles from history in front of blacks talking about "discrimination of the past" and why things had to change. They shake their heads yes until I tell them it was about Irish whites. They get confused because nobody told them English whites discriminated against all other whites and vice versa. Refrain was "one thing called white" vs "everyone else." Then, they either adjust their thinking or go into denial.
Even so, I still don't have to go that far. See, intellectual white people that love computers are called "nerds." We experience the exact kind of systematic discrimination and profiling you describe. We're filtered out of upward mobility in most business circles due to lack of social fit. We're excluded from all kinds of social activities because we're different. We're shoehorned into jobs they think are best for "our kind" then not given gratitude or equal treatment by upper management. I'm so good at blending in with normal people that I get to hear all kinds of negative stuff by whites and blacks alike about what they think of my social class. White "privilege" among "nerds?" Only if the privilege is one kind of job in a specific pay range with less of everything else. That's not a privilege. It's like a peaceful, passive form of indentured servitude. Similar to what blacks claim about many of their job results.
So, yes, many whites do face systematic discrimination if they're not of the popular variety in terms of appearance, speech, ethnicity, or whatever. This has been true since American began far as I can tell. It goes back to the battles and issues I read about in World History among Europeans. You've probably seen it yourself but explained it off as... typically... "isolated and not systemic problem." No, it's just a series of isolated problems that repeat upon specific attributes throughout the system by white and non-white oppressors alike. Not systemic or regular, though. Just coincidentally pervasive. ;)
Note: I upvoted your comment because it's the kind of claims disconnected from reality that people need to see addressed with specific counterpoints.
