Relative. The mehr thing isn't of highlight with an ajnabi. What I see in what you describe is a clear aversion to Somali men and/or culture. You need to interview one of these chicks you speak of and candidly ask her why.
Patriarchy keeps the Somali identity in tact. Throughout the history of humanity, time and time again one tribe has annihilated the men of a rival tribe and taken the women for themselves. If I'm being honest, it's pretty much the story of the Somali and wider Cushitic speaking people's ethnogenesis.
It follows then that women do not have the same urge to protect the tribe, and throughout the course of human evolution, patriarchy alone has ensured the survival of each particular tribe or ethnic group. We can even see this behavior repeated throughout the animal kingdom e.g. a lioness shacking up with the strongest lion even though the nigga done killed her cubs a hour ago kkkkkk.
Somali men are obviously not the dominant males in the West, hence the disproportionate amount of Somali women who gravitate towards who they perceive as dominant i.e. cadaans and other filth. We cannot ignore a hundred thousand years of evolution, thus making the patriarchy an unfortunate but ultimately necessary solution.
