I believe that the bigger factor is economics and the continually shipping of American jobs overseas over the past 30 years. The level of damage that did to the middle class (the largest segment of American society) was bound to show up in peoples behavior. While white Americas were probably longing for a purely white America, they were outwardly fine with its changing demographics until they suddenly had no food on their tables. A hungry man is after all an angry man.leaving Guyana just like there is a reason many from other parts of the world end up leaving their homeland and the one common factor is that the countries we left was for lack of a better word, shithole countries.
That is a pathetic excuse and a lie. This country was a good deal more racist in the 80s than it is today. Then bashing black people and calling us welfare criminals poured out of Ronald Reagan's mouth. George HW Bush's campaign was such that the Indo KKK would have been proud as it criminalized all black men. Blacks were seen as subhuman. Open racial jokes were perfectly OK in offices/
Almost NOTHING was said about this and when blacks complained we were accused of having a chip on our shoulder. Even as people boasted about their right to exclude blacks.
Now "nonracist" white people are running around trying hard not to look racist. Thank you Donald Trump. Your vulgarity and that of your core base has forced the USA to look at itself in the mirror and stop pretending that it isn't what it is. They are actually now looking around their offices and wondering how come it looks like Helsinki instead of NYC.
