NAIROBI: The most useful thing about the tribe is that it is a weapon in primitive societies. By the same token, it is the most useless thing about the tribe in modern times. You can employ the weapon of tribalism against other tribes, regardless that you have justification or not. This is why the political class invests in tribal hostility.
A governor somewhere may accordingly deflect public debate from the main issues to bring in a cultural angle that has nothing to do with the great questions of the day. A tribe that does not circumcise its men may be ridiculed.
