Unfortunately, there are those that HAVE to play the race card and who will use all manner of guilt and arguement. They do not seem to realize that it is THEM that emphasizes race as a separateness rather than a uniqueness.
I have posted before that my father is American Indian and grew up on a reservation. He has had to deal with racism all his life. I myself have dealt with it from people who think I am white and hate American Indians, and American Indians themselves who hate those that look white and live off the res.
I was raised in a home where we were taught to be proud of our heritage but not to wield it. In other words, don't use it as an excuse for our own behaviour, and don't empower prejudism by using it against others.
In Arizona there was a big debate over an area that had been named "Squaw Peak" long ago. The Indians wanted it changed because the word Squaw is actually considered derogatory by many. Nobody really thought anything about it until the Indians emphasized it, therefore empowering those that would make it into something negative.
Look at what we did to the Japanese during World War II. The Holocaust. The civil wars in Africa. The Crusades. The genocide in Iraq. People will invariably fight against that which they consider different, and as long as we emphasize and use the "differences" rather than celebrate them, there will always be those who are angry.
Collecting pieces and pictures of your heritage is a wonderful thing. It's part of your past, a past which cannot be changed, and something to be proud of. Your people survived and prospered out of a tragic series of events, just as the American Indians and many other races and cultures through out the world have done so for centuries. Political correctness has made us feel guilty and we want to hide what was done like children, rather than keeping it alive in a healthy manner so that we don't do it again.
We are all innocent of what was done to and by our own people in the past. Be proud of who you are and where you come from while respecting others and you can't go wrong.
Just my humble opinion.
