One of my degrees was earned in Boston.
Boston, late 70s-80, was the most racist city in which I've ever lived.
However, none of us should pretend that the integration of public schools in Mississippi went off without significant issues. Of all states, Mississippi would be a case study in the problems with integrating public schools.
Your point is like saying some northern colleges resisted admitting black students. That's probably true. However, I don't recall that any of them involved 3,500 troops, 500 law enforcement officers, riots, and a student who required 24-hour protection from U.S. Marshalls.
BTW... some of the black kids that I went to Junior High and High School with are customers and friends of mine today.
I was a Boy Scout as a kid... it was the best thing that ever happened to me and I support the Boy Scouts today and have friends that are Scoutmasters. GOD bless you for being one!!! Merry Christmas to you and yours.
