I guess here's how I think about it.
There are some fairly vast cultural differences in the United States between, say, a rural community in the deep South and New York City. But these two groups are nevertheless united by an over-arching American culture.
That's how I see the relationship between all communities that are either European or of European descent.
How many cities/states have you been to? I never had the courage that many of my trainhoppers friends have to ride the rails and see the country. I truly regret not doing it but I've listened to many of their stories, and done quite a bit of traveling myself.
I've spoken before about my upbringing, moving around a lot as a kid, young adult. (I still move constantly) born and spent my formulative years in a Vietnamese neighborhood, ended up going to a mostly all black magnet school, spending most of my career in kitchens with illegal immigrants, then ended up in a smaller city oil town for high school.
Now you could say that that smaller town had more people "like me" dictated by skin color, but I truly never felt apart of it.
Plenty of rich people thanks to it being the home of ConocoPhillips, and plenty of white trash as well. The air of inclusivity kept everything nice on the outside, bland and soulless on the inside.
It was that small city that pushed me towards radical anti racist groups, told by teachers the book on Buddhism I was reading had satanic undertones, adults openly talking about interracial relationships with spite. I was told by family friends that I should never be in one. The golf course my grandparents bought didn't allow blacks membership until the mid to late 90s and it was openly spoken about. Everyone was extremely proud when there was the first token black member lol.
The town is still mostly the same, small pockets of Mexicans have moved in, but they're ostracized by the white community, there is little encouragement for Mexicans to assimilate and why would they? I stopped by a Mexican place when I was in town and openly heard the words "wetback waiter" at a table next to me.
It's reasons like this that I'm pro multiculturalism, the exchange of cultures and ideas that shape our nation. Look at the Chinese influence on San Francisco and DC, the many many cultural variances in one of the worlds greatest cities in New Orleans, Cubans and Jews in Miami, so on so forth for everyone.
Much of this hatred is ignorance, and I, in my own ignorance grew up hating America. We're all victims of circumstance, and where we grow up is the biggest circumstance of all. I grew up hating America until I travelled more and saw her, I saw how groups of immigrants all over the world came to the United States and built up some of the most beautiful cities in the history of the world through the strength of our diversity and by putting aside our differences to better our towns, cities, states and our country as a whole. That's the overarching American culture.
To quote the great Dropkick Murphys "
And the boys on the docks needed John for sure.
When they came to this country he opened the door.
He said "Man I'll tell ya, they don't like our kind.
Though it starts with a fist it must end with your mind."
Say hey Johnny boy, the battle call.
United we stand, divided we fall.
Together we are what we can't be alone.
We came to this country you made it our home."
