I never claime, that Rias or Sona said that is not importan. Rias take it as pride to be high-class-devil of pure blood noble family it is as you said. But if the white race is going to mixed with other race, the purity of the white or black race would be gone in the future, because they race are now mixed races. Sure the demon of extra relam will be pure devils. Compare America in 50 or 60 in South State how the American with black skin were treated. This change when the time passed. Are you telling me that only white American or American and those American which are mixed race are not American ? Grafiya´s family has to politcal power.

When the orginal Satans died, the Bales were the gread king their support king system, because the devils like Shalba, Cateria were only pawan without a politcal power. When the time passed

Sirzechs, Ajuka and co fought the devils of the old Maou faction and gained politcal power. They estabilshed the evil piece system, because the wanted to make sure, that demon kind could survied. They allow reincarned devils to became high-class-devil when they are worthy. Ise through his actions and deeds became importan for the devils. In just one year he became a high-class devil. He is engeaged to Rias a pureblood-high-class-devil of noble family. It would take time.In current system no mixed blood devil is allow to inhernted  the noble purebloods clan. So this regard Sona will not be allow to marry Saji, because her clan will lose their noble status. Even Zakram want, that Ise became a Satan despite the fact, that he is a reincarned devil.
