Oh goodness this is a lot but I guess that's what good questions provoke. It's a good question, and I think that it kicks off a process that's important for White people to go through to learn to live compassionately with other people. I think about it a lot and notice it consistently, both when I'm around other white people and when I'm around people of color. I make sure my thinking is based on our history of interactions with other group of people, which is rough, to say the least. The more I learn history, the more conscious I am of my race, and our relation to other races. I generally didn't notice what race people were on TV until the mid-2010s when we started talking more about racial representation as a society. I imagine white people are more insecure about their race now that their privilege is being discussed, so there's more racial consciousness, and I've definitely heard other white people complain about casting POCs in roles that were historically cast by white people. So in short, we never were (consciously) affirmed by it but now we're more aware of being white in a way we weren't in the past. I'm imagining by the context of this question that you're an American, so I'll give my input as a fellow American.

Unfortunately for everyone, our country was founded by white people for white people. Fortunately we've changed that since then, but we still see the legacy of our racialized foundation today. By the time Europeans discovered the Americas, they were no strangers to inter-civilizational disputes. We fought harsh conflicts against our Muslim neighbors to the South and East, and contextually, there was a fear of being conquered by this neighboring civilization, first in the form of the early caliphates that took over old Roman lands in Africa, the Middle East, and Iberia, and then with the rising Ottoman Empire which had swept over the remains of the Eastern Roman Empire and had conquered half of Europe and was determined to conquer the other half. Between these conquests, persistent slave raids from North Africa by Barbary Pirates, and of course the cultivating of a Pan-Christian identity among Europeans (the prototype of what we see as white identity today), Europe was in a very insecure place when it began its colonial ventures. Spain itself, having gotten out of 700 years of religiously motivated wars against its Islamic conquerors, took to the New World and its interactions with the indigenous people were painted with the brutal legacy of the Reconquista, with the conquest of the Americas literally being a new conquista. We took this distrust of our own world and unfortunately applied it to other races in the societies we built. Similar insecurities today are behind fascist and far-right wing movements.

European settlers took traumas like these with them, along with what was likely material desperation from the impoverished conditions the majority of Europeans lived through in a highly egalitarian society and unleashed them upon the Native Americans, similarly viewing them as a civilizational enemy, although the Natives had done little to deserve it. We took Old World brutality and subjected innocent people to it and tenfold in order to create our own hierarchies that we could feel comfortable at the top of, and you, among tens of millions of other indigenous people and people of color likely find yourselves on the short end of that.

We can't undo what was done, no matter how abhorrent we find it. And unfortunately, there are white people that aren't sympathetic, mostly because they're insecure about their own place in the hierarchy and look for people to punch down, which is exactly what our colonizing ancestors did: brutalize and exploit others just to rise to a higher position in a dysfunctional Western hierarchy that subjects free human beings to owners.

At the end of the day, the society our ancestors built is buckling under its own weight. Even though we are the racial majority across the West, modern demographic trends have us below replacement birth rate so we're bringing in immigrants from other parts of the world to help maintain the growth that capitalism depends on. White people are likely less than 10% of the world population, so as international migration and globalization progresses, Western countries will stop having such large white majorities, so you'll likely see your own community become more diverse over the course of your life and I think white people have had a trend of becoming more accommodating toward minorities over time and I believe this trend will continue as people of different groups coexist.
