The study by Capelli et al. has concluded that the contemporary males of Malta most likely originated from Southern Italy.[19] The study also indicates that Malta was barely inhabited at the turn of the tenth century and was likely to have been repopulated by settlers from Sicily and Calabria who spoke Siculo-Arabic.
If we're going to have policies in the far future which take into account race we'll need to go about this scientifically
How I would practically determine someone's race is having them be evaluated by a set of professionals which if they pass and self identify as white is fine
In the contentious cases you would make use of DNA tests and various criteria like the degrees of admixture which are tolerable etc. after which the professionals give ok or no
If you want to be autistic about it, use the racial hierarchy system of the Spanish Empire, there are ranks and categories for every admixture and purity.
like alot of people here will say Ashkenazi arent white yet their genetics show they are closer to white genetically than some other groups that we would definitely consider white
