"It is wisdom protective of ethnic communities when people join parties with different ethnic leaders which cannot leave them out of government or plot genocide against them," he said.

He added: "It is clever communities never put all their eggs in one basket. When a community is able to join parties led by other Kenyans, it is protected when it is represented in the leadership of the ruling party as well as the opposition. If a community has its leaders in all parties, it will share in the victory of the ruling party and that of the opposition when it come to power."
