I’m more annoyed that these government healthcare marketplaces are asking people their race in the first place. Really don’t think anything should be, including job applications.
I never (in the US) have understood why those questions include separate questions for race (seems to be like white or black or asian) and for ethnicity, including a really odd question about Latino or non Latino.
Why those questions, but no Danish vs non Danish, and so on?
It's because latinos can be white, black, or native - and historically most people tracking these data wanted to group latinos independently of non-latino whites, blacks, and natives.
1. one of the main points of the ACA that hasn't been rolled back is that they can't worry about pre-existing conditions anymore
2. even if they could, it would be pretty illegal, I think/hope, to then be like "Oh, well your sickle cell anemia is going to be paid for differently, because everyone knows black people statistically have more of that.
