suppose a rare disease is only well researched in a few white families. lets say, the mennonites. curing the disease is possible, but expensive. should everyone else be forced to subsidize it? what if the markers are known and parents choose to have kids anyways even though they have the markers.
does the situation change if its sickle cell anemia?
this is a real thing. Gaucher's disease, while anyone can get it in principle, is almost entirely a disease that afflicts ashkenazim. the treatment is cerezyme, which is one of the most expensive drugs, and you must take it for life.
and you missed the comment about sickle cell (only affects west africans and people of west african descent). which is now curable, but VERY expensive to cure.
If you’re dead set on arguing about an arbitrary imaginary definition of a word, the world is your oyster. You can say sickle cell or Methuselah Syndrome or Tandy’s Malady, it’s all gravy if you can convince your mark that whatever you’re talking about is the same thing as the broad concept of healthcare.
im not the one arguing from a made up definition here. almost ANYONE would consider cancer, rare cancer, sickle cell treatments, and gauchers treatments "healthcare". its disingenuous to put those outside the bag of things called healthcare just because its inconvenient to your worldview
