Abusing diana back home is a new thing tbh most likely influenced by bollywood & arabic films. Before the war, who did that? No one. 
And the new songs geeljires put out are praising light skin ”midabkaaga nuurka”.
However, diaspora guys are exactly like the other madows in the sense that they go for the non african girl. This girl was probably ignored by geeljire guys & saw lighter geeljire girls get praise. Its different from other madow cultures where even your family tell you negative things about your darkskin. I can’t really speak for all geeljire households, but i still think its accurate to say that your family aren’t the aggressors tbh. Its who you meet outside & how they value you. 
For most geeljire girls i think the discrimination is not direct like ”dhuxul baad tahay iis cadee”, but how much attention & praise you’re not given cause you’re darker.
