Has ANYONE, i.e. the CDC, the WHO, or any other data-gathering organization EVER linked the incidence of COVID cases to blood types? Most of us on this site have consumed all matter of flotsam and jetsam from these jackasses, but has anyone ever tied COVID to the mythical blood lineages of Cain and Abel (and, oh by the way, Cain is the supposed spawn of the sperm that dripped off our Creator's leg)...

Asking for a "friend." KEK :)
