Race does not exist, it is an invention by people who lack the intellectual capacity to see people as individuals and treat them that way.
We are all individuals, your ancestors do not define what you do and how you live your life. You do. Stop using some dead people that do not exist as some sort of reflection of your current character. You make your own choices and have to live by them.
When pressed to put my "race" on some form I usually refuse but when absolutely legally required I put Native American. Because I define my "race" based upon myself as an individual and I was born in America and I, as an individual, am native to this land. I respect my parents for their upbringing but my actions are my own, not theirs. Nothing my ancestors have done are anything I have done unless I choose to do them myself. There is no pride nor shame for the actions of my ancestors or any race/country/inventor/slave owner/slave of the past who also happens to share common ancestors.
I am an individual with my own thoughts and ideals.
Race is not a bad thing by itself.
It's a good way to categorize the genetic specifications of an individual.
What's bad is to think that races are important over the evolution, and thus the judgement, of an individual.
Races are just a tool for scientists, biologists and doctors. Not a way to judge individuals.
If you took the DNA of millions of people you would not be able to scientifically assign a race based upon combinations. And even then, what use would it have at all?
It's just like all of these people watching the Super Bowl yesterday rooting for "their" team, feeling happy when their team won along with the satisfaction of victory. You didn't do shit. You chose a team....wow. You accomplished nothing. The people on the team and the coaches, owners, etc. actually contributed to the win. You sitting at home yelling at the TV did not change anything. You were not part of giving that team of players a victory.
Or people being proud of where they live because X famous person lived there once. You're not famous. You didn't accomplish what those people did. You just happen to exist at a location where at another time someone actually did something.
