Before 1964, the Southern faction of the democrat party was entirely racist. The Northern faction, not so much. But the Northern faction still had to kiss up to the Southern faction to win any national elections and to get anything done
When you looked at how the North reacted to integration in the 1970's, I think you'll see that they were just as racist as the South.
The most racist guy I've EVER met was a Chicago Democrat who'd moved to Michigan and worked on the assembly line for GM.
The way the scum of the Earth dimocraps took over the North was to import Hundreds of Thousands of Blacks to the Cities by promising welfare.
There was a Supreme Court ruling on that, I think. Maybe it was based on voting status. Whatever, but they got away with it.
They simply loaded up hundreds of thousands of Black people from the very poor Rural South and shipped them north. Every one of them equipped with at least one voter ID card.
Look, I don't care if they had been Appalachians as white as the driven snow. Or any other group of a different race, but the fact is this.......
These people were very poor, very unsophisticated, very backward, very uneducated, very disease-ridden, sometimes very violent, and very new to the neighborhood.
I lived in Cleveland (outside it, actually) and I can tell you, there was a great deal of prejudice in those days.
But not just against Blacks. It was jokingly noted that West (By God) Virginia taught the "Three R's"..... Readin', writin' and the Road to Cleveland."
The Croatians hated the Serbs. I guess there was quite the little war while trying to board ships in the Adriatic to make the voyage to the US. I heard that the Serbs were pouring hot water on the Croats trying to board the Ship. What ship? I dunno, the USS Kishka?
The Italians hated everybody. Except other Italians. And they spent a lot of of time proving it by shooting each other and planting bombs in their Italian friends' cars.
The Germans stayed aloof and mostly drank a lot of beer.
The original inhabitants moved to the burbs and called everybody else names.
And not really inaccurate ones, either.
I went in the Army in the 60's and took the Bus home a lot. I could actually pocket money out of my travel pay.
But I only took the Bus to Cleveland a couple times. I swear to you, I thought they were making a Tarzan movie in Cleveland when I got there. There was so many Black people, I couldn't believe it. And they were being loud, rude and pushy.
So I'm not letting the North off the hook, but I'm telling you.... They had their reasons back then. It wasn't really racial prejudice as much as it was not wanting to put up with a bunch more new DPs (Displaced Persons) again.
Shit gets old. Especially when they don't want to 'fit in'. As in, take a bath and learn to speak the language, to start with.
Your two Northeastern Cities (NYC and Bawstan), north of Philly, didn't get the onslaught of Blacks that the Rust Belt area got. And no, that wasn't an accident.
