Whites essentially quarantined blacks up here; there has never been integration (and I doubt there ever will be). It exists only on the books; the reality is much different. Here in NJ we’ve had our own miniature version of the South Boston busing issues; any white population that even hears a rumor of busing withdraws their children from the impacted district.
Over the years, I’ve traveled the nation on business. The northeast is far more divided than the south.
I believe racism is greater in the north too. I would hear things up north that I never could image hearing in the south. I’ve known blacks too that have told me that people are much nicer to them in the south. They would never want to move back up north.
