I know the Moryans in Hamar hate Isaaq about sensationalising Wanlawayn incident as all moryans in all clans started to see hawiye as an armed minority in a sea of UN armed majority back then. Alot of their animosity comes from that originating incident which has instigated new trends to develop from it and harming hawiyenimo glory.
Shit is always tense between Hawiye and Isaaq even in irirism needing Djibouti to mediate always to make sure it doesn't get out of hand or they both deflect to darod(a shared enemy) or some internal clan matters.
Hawiye did call them Qaldaan also because their fudeed(impulsive and speak to direct, to open minded, easy going, not the hos ka cun old urban values but with a nasty twist post 91 thug mentality moryanism) that emerged when I was there.
