It is unfortunate that the young lady had that experience, but prejudice can be found anywhere, but it is not as common as it once was. It seems from reading the article that this young lady was raised in a very sheltered environment and was unprepared for the Real World when she entered it. Its possible that her over reaction caused the other kids (yes fresh from collage makes them kids) to play it up more than they ordinarily would have.
When I was stationed at Pearl Harbor in the early 80s a Department of the Army race relations team arrived to investigate racial discrimination in the 45th Transportation Group. They were disappointed. Over half of the personnel in our company (5th TC (HB) were married to or dating a person of a different race. They could find no racial prejudice in promotions or disciplinary actions. Private interviews showed no hint of racial prejudice. They experienced much the same in the other companies they investigated and had to cut short their Hawaiian paid vacation they could not justify holding classes to fix a nonexistent problem.
I had dated women of every race during my 40 years of having a social life. My late wife was half American Indian. I experienced signs of prejudice only once when living in an apartment complex that had gone Section 8. My girlfriend at the time was Black and several of the Black men we encountered did not seem to approve. We ignored them.
Wow thanks to the troll, I know I've been here for two years now :D
