Discrimination is more proper word then racism.
I would lie to myself if i deny that it exist. 15 years ago there was discrimination among Qataris. Arab tribe, Bedouin, persian,Yemenite, afro qataris weren't all treated alike (or let's say didn't have the same chances). Now, things are changing gradually.Qataris are integrating socially . I think with proper education and awareness , within the next decade more people will realize that some attitudes are not acceptable in a civilized society. With People like DG around , I'm determined that this will happen
