Humans world wide have the same tendencies. Fathers commit fornication with daughters, mothers commit fornication with their sons. Brothers and sisters, uncles and aunts commit fornication with their nephews. Stepfather's and stepmothers commit fornication with their stepchildren.
It is not only in Kenya. It is just that these ones have been exposed.
In Nigeria, under aged children have been forcibly married and some instances exposed recently.
This is the result of sin and all mankind is united in committing sin.
The remedy is that men should repent and return to the source of sanity as sin is insanity.
