This poster wasn't commissioned by any organization with a medical background, I can tell you.
In fact, mal information like this can get people killed.
Why do you think there is a constant drive for more black blood donors?
It's because blood type is even more divisive than race; the reason O negative "universal donor" type blood is so coveted is that it is usable across racial lines, and across blood type (antigen type) lines within races because it contains no antigens.
If you put white blood in a black man, unless that white man has a "universal donor" blood type, the black man will die.
Only about 7% of the global population is O negative.
You are a lysenkoist, and you should be publicly stoned to death, and your carcass displayed on a gibbet, before your stupid ideas can hurt anybody who matters.
