Aren't these statements their own subtle (yet just as potent) forms of bigotry?

In the first place "race" does not exist on the biological level so there is no such thing as a "pure" anything. The notion that there are "racial genes" or "racial blood" is a naive delusion not based on science. There is as much genetic diversity between any two individuals of the same traditionally defined "race" as there is between them and someone of a "different race".

I have placed those terms in quotation marks because what we call "race" in humans is actually not a biological distinction. So what you are imagining is an arbitrary inclusion in a society based on superficial appearance of individuals. Who will determine who is and isn't a part of this "pure" group since there is not way to selectively categorize people biologically?

And how do you avoid discriminating against those who are excluded based on these arbitrary definitions?

When others have brought this topic up before, my first thought was humans are like cotton. You can have a soft cotton shirt, or very rough pair of jeans. They are the same material, but they feel and look different.

They have different colors. But they are the same. Do you know that 100's of thousands of people died, because they would not give blood to different people, before Pastier recognized the different blood types.

But not only did they let people die because they did not mix blood from different races, but also men and women. I think medically the only reason race is used because some type of people, depending where they live, and how they grew up, have genes that are bad, and if two people with the same bad gene it could harm their child. Other then that there is no difference.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
