I dont understand

So today i went to a greek program which was titled the minority forum hosted by the ladies of Sigma Gamma Rho Sorority incorporated. This program consist of a panel of students who are on various Greek organizations on campus, the goal of the program is for people who are Greek and those who are not to come and ask questions that you have been dieing to ask. So i get to the program and the only thing i see is members of nphc which are the African American organizations and also Nalfo which are the latin base orgs. Well to make a long story short it was not anything informal about this program because all they were doing was bashing each other and saying like why this one should not step and the roots of this and that What i do not understand which is the title of my blog is why do us as in minority's especially on this campus have such a rivals it does not make any sense if anything we are the ones who need to band together because it is not many of us, all this fighting and carrying on just leads to the stereotypes which are proven to be true because of the example we are setting.
