My mother would prefer me not only marry someone who is black but from the same country and also from the same tribe group within the country. When I was younger, she was extremely strong on the message. Imo, it felt like she viewed things as if we were back in our home country versus multicultural London.
Regardless, I've never ever had it in my mind to just date people with the exact same ethnic background as me. Whilst I'm open to them, I'd never severely limit my pool of guys. It seemed crazy to me that I would deliberately overlook someone who was an ideal match for me just because he was from somewhere else. Even my mother is seeing things more how I do lately, although I know she still has her preferences.
