Wahaj Faridy, According to pakistani magazines like "The Herald", untouchability exists in muslim society also. That is why many of them are becoming Christians there. The magazine quotes many muslims as saying that if they serve tea or coffee to any "bangi caste", be they Hindu or muslim, they will drop the glass in fire, before and after washing it, without touching it. Many muslims from Dalit castes, find that muslims from other castes do not wish to marry them. You can investigate. You will find this to be fact.
