You should understand the importance of those cultural practices (cleansing and wife inheritance) before dismissing them.

After a woman's husband dies, she must engage in sexual intercourse without a condom with a “cleanser,” often a non-relative of the deceased husband, to remove the impurity she is believed to have acquired from the death of her husband. A condom is not used because the practices are considered incomplete unless fluids mix during intercourse. The Luo believe that the death of a husband confers impurity upon the widow and restricts her from participating fully in certain social events. Sexual ritual is thus performed to cleanse her and fully reintegrate her into normal community life.

After a widow has been “cleansed,” she is expected to be inherited by a man, traditionally an in-law. Inheritance is important in that the designated male assumes responsibility for the social and economic support of a widow upon the death of her husband.

For a young widow with children, inheritance by a brother or cousin to the husband allows for continued support by her husband’s extended family. Widows without children or with few children are expected by the extended family to bear children, particularly sons, who would continue the lineage of the deceased husband.

Also many women are widowed young, and fulfillment of sexual desire is a major reason for being inherited.

Aside from the initial cleansing ritual, widows, as well as married women, are expected to observe other sexual norms common in the Luo community. For example, they are expected to engage in sexual intercourse during the establishment of a home; during agricultural cycles such as tilling the land, planting, and harvesting; and when participating in the funeral or marriage ceremonies of some relatives. In each of these cases, a widow must find a sexual partner to help her fulfill these required rites. Fulfilling these sexual rituals often means engaging in sex without a condom, because the practices are considered incomplete unless fluids mix during sexual intercourse . Women engage in these practices to conform to societal norms or because they are compelled to do so by their husbands’ families, their own families, or the belief that engaging in the tradition will ensure that they or their children will not be ostracized or face illness or other misfortunes (chira).

If a woman does not have a resident partner with whom she can carry out ritual sexual practices, she is expected to look for a man with whom to observe the sexual ritual. An inherited widow can observe this ritual with the inheritor when such occasions arise, but a widow who is not inherited has to seek another man with whom to observe the sexual rituals.

As you can see those practices are important to ensure the welfare of the woman in luo society.

A man or woman does not exist in isolation. They are part of the larger community which is governed by traditions and customs, and no one knows about those societal matters better than the elders. Therefore elders, not just luo ones, have a duty to remind members of their communities on the correct procedures to follow during events such as deaths, marriages, initiations etc. Or should we also fault our judges when they remind us what our laws and katiba say regarding the procedures to follow when certain events occur? The luo elders are just telling you what the "luo katiba" says, its nothing personal.

Heshimu wazee. They mean well for the community....
