Southern Europeans have minimal to none moorish admixture and the few who Do have it from prehistoric times which isn't present in their phenotype at all also ancient berber/arabs were as caucasoid a Europeans so I guess having berber or arab admixture doen't make someone less white the mixing between subraces/ethnicities of the same race isn't like the mixing of two different races,I don't personally consider the son/daughter of a pale lebanese Christian and an European or white American "racially" mixed only ethnically or subracially or wathever
