Moors were both Arabs and Berbers. The invading force that was turned back ostensibly by the leadership of El Cid was Berber. They remained in the south of Hispania until expelled by Isabella, though many publicly converted to Christianity as they saw Hispania as being their home for generations.
By family history I an 50-50 Irish and Calabrese but while the Irish side is 43% by DNA with the rest split between Scot and Welsh, my Italian side registers 23% with the rest split with Cyprus, the Greek Isles, the Levant and Asia Minor. My family record going back to 1680 shows only Calabrese ancestors, but the rest came way before. So am I white? By color, barely. By blood, who knows.
An interesting aside. I was teaching Reconstruction to my Woodside 8th graders. We were reading some of the Klan founders’ writings. One gal, a Colombian named Joanie blurted out “ You’re in the Klan.” I asked her why she thought that and she said
“You’re white.” I asked her to come up. She hesitated but her classmates persuaded her. I asked her to roll up the sleeve of her sweater. I rolled up my shirts leave. We held them next to each other. I asked her,” Joanie who’s whiter?”
She was and she was befuddled. Her whole world view about color and race had been shattered. I piled on a bit by telling her “ I’m only half Italian. You should have seen my dad.”
