Dragon, I shall not quote your post in this reply. Unacceptable, ugly and not funny. These officers risked, and some lost their lives at a time that racism was rampant. They are a part of the reason that you are a free man. If you can't show them some respect then at least keep your mouth shut.
I too will ask you to relax a bit and stop with the knee jerkin' responses. Also, what society views an "racism" today may have not been back then. Separation of the races and social classes was accepted by most people involved.
My grandmother graduated college in May of 1943, she had to wear white gloves her entire Sr year in preparation of her being considered "upper class" and it was suggested to her to never be out of sight of her spouse or her own father, and to not frequent public places with those who were uneducated. She was expected to wear a skirt, wear those white gloves, and to associate with the educated. That is the way it was, nothing evil about it.
Learn to separate historical and factual events from your present day views on things and you will be able to see things in a much different manner and more so you'll be very hesitant to grasp on to the populist views which have become so very abundant. What you and other believe was rabid "racism" was very possibly nothing malicious but rather "just the way it was". The lines between the north and south were just as heavy, as was the Philly and Jersey boys, as was the Catholics vs Protestants, as was the German immigrants vs Irish immigrants vs Italian immigrants, as was the urban vs rural, as was the educated vs uneducated. It was not just a black vs white thing. Trust me.
