Right around the time that I was born my family left their apartment in the Bronx (NYC) and moved to a city just North of NYC, into an overwhelmingly white area (which has since been integrated by court order). We had one African-American kid in my elementary school. He was actually in my class. I remember that his dad was an attorney. The abuse that this kid took through 5th grade was horrible. This was the early 1970's.
In my teens, neighborhood kids (some who were, at the time, friends) would physically attack any minorities who came into "our neighborhood". This was the late 1970's.
At 17, early 1980's, I joined the Marines. This raised the level of racial insensitivity that I witnessed to a whole new level. I enjoyed my time in the Marines, but some of those Southern boys were still fighting the Civil War.
Mid 1980's i started my 25 year in law enforcement in a predominately African-American city that borders NYC. Wow, to sum it all up. There were still cops on that job that came on in the 1950's and 1960's and they had an absolute hatred, a hatred for African-Americans. It was a very, very tough environment for a while.
But eventually, I've seen people be more accepting of other races. But personally, like roothog66 said, they still feel it. They just don't wear it like a badge of honor anymore.
