As people bring up Asian countries in other comments, I think they miss the point. For all I know Chinese could as well be racists as some comments say. However, consider this: blood type is important in Asia yet most people in the USA do not even know their blood type so, we could conclude it's not important here. Now, imagine a movement to force blood type diversity took root in the American tech. Then, would it be still hard for you to picture someone who does not believe that the blood type diversity is a good in itself yet is not a "burahara"-type bigot who thinks the B-type people are inferior?
