The contrast between patriotism (good) and nationalism (bad) is illustrative. I don't know how one could be a patriot and not be a nationalist as well. Nationalism has been given a quite negative slant in the last 40 or 50 years. I suppose that is because some of our worst enemies have been nationalists, so therefore we should not be.
For some leftists (internationalist socialists) patriotism is as grave a sin as nationalism. They at least agree that the two terms mean the same thing. Patriotism and nationalism have potential negative aspects, for sure. "My country, right or wrong!" is never good foreign policy.
Race hatred is clearly a bad thing. We have seen plenty of that (and not just in the US). I would describe "race hatred" and run of the mill "racism" as different points on a continuum. Race hatred leads to lynching. Ordinary racism leads to segregated suburban communities and schools. White suburbs are not in the same category as KKK terrorism.
Racism has resulted in social structures that permanently disadvantaged racial targets. Cutting blacks out of the real estate expansion of the post-war boom hardened economic disparities. Racial discrimination in employment, accommodations, education, and so on, further cemented inequality into place. Then there is the feedback loop. Well off people don't usually want to live with poor people which leads to further racial separation.
Did I get this from critical race theory? No, just from reading history.
I don't believe in white supremacy, white fragility, and the like. I believe that people are far more alike than they are different. One can count on groups of people pursuing their own advantage. If they happen to be in the majority, happen to have more money, happen to have more power -- then they are going to come way out on top, and those who don't have those assets probably won't.
Only SOME white people had all that. We have a wealthy ruling class and a smaller prosperous middle class. Together, they make up maybe 20% of the population. The rest of the population is working class, and generally they have not done all that well, historically or recently. The majority of the working class has been white. Whiteness didn't help their class status.
Racism blames the losers for not coming out on top. That's just stupid, of course. Poor people, white, black, hispanic, asian, or what have you are usually poor because their parents were not members of the ruling or prosperous middle class. The escalator of upward mobility doesn't start on the basement level.
"Yes but... There are millions and millions of white people who own homes that are worth a lot of money. They are getting rich while we, who couldn't get a mortgage, are getting poorer."
Not so fast. Most working class people do not own the homes they live in. They are in debt up to their ears for much of their lives. They don't have clear ownership of their house until they pay off the mortgage.
House, car, college loans, and credit cards are a sort of indenture. If you want to keep your house, car, and the stuff you bought on credit, you had better be a compliant employee. IF NOT... there are serious consequences. Then there is that degree you worked hard for, paid for on credit, and may not now be able to pay back. Again, there are unpleasant consequences for being a deadbeat.
The people who deserve the envy of the poor are prosperous middle class and ruling class people with enough money to actually pay for the large properties, cars, educations, travel, and so on that they enjoy.
I'm not sure there is a cure for racial hatred. Containing it may be all we can do.
The best bet to reduce racism is for working class people -- black and white together -- to recognize they are in the same sinking boat. It's mostly about money. Follow the money, as the saying goes. Economics explains why a few are on top and most of us are not.
Trying to change racial attitudes in a vacuum, or because they seem like bad manners, is just not worth the effort.
