@Fay if Somalis prefer thinner facial features, that isn't self hate because those are features found within us more commonly. It's actually a sign of self-love. Of course, said features should not be made fun of because they are also creations of Allah and thus perfect.
It can be considered self-hate when those with X features trash X features. So somalis can be colorist since we are darker in complexion but featurism is just preferring what is biologically more common in us, and natural for us. Don't confuse the two.
