I see a lack of perspective in these responses on both sides of the issue. Not to mention the incorrect generalization the essay itself is based on.
Whites have historically taken advantage of those of other races and ethnicity. This is not myth. I have two degrees in history, and this is a consistent theme as Europeans explored other continents. That poor whites and those of certain religions have also suffered at the hands of those of their own race, while true, does not change the former. This racial distinction also appears in the U.S. constitution and the massive existence of slavery in the southeast. All factual realities. Racism still exists in this country, but the difference is where it exists most and who are the likely racists.
This brings me to the premise that Democrats and white are the problem, a theme in this essay that is false in scope and scale. Whites who are racist tend to have less education, but there are prosperous rural whites who are also racist. It’s as much about geography and population density as about education. Whites who are more inclusive and tolerant tend to live in the ~125 metropolitan regions of the country, which represent 80 percent of the population. They are more likely to see and know those of other races and ethnicity, and that typically makes them more “liberal,” noting that the original meaning of liberal is open to new ideas — also the source of the term liberal education.
Keep in mind that white supremacists typically have low self-esteem, and they use their anger and hate to pretend they are more important than they feel. White privilege isn’t what it used to be for them and they despise their less exalted status. Voting for Trump calls into question the moral standards of those who did so. He campaigned to those most likely to be racist.
